Bui, Trinh T. L. Vuong, Jin Tae Kwak* - -**Abstract:** Slide-level classification for whole-slide images (WSIs) has been widely recognized as a crucial problem in digital and computational pathology. Current approaches commonly consider WSIs as a bag of cropped patches and process them via multiple instance learning due to the large number of patches, which cannot fully explore the relationship among patches; in other words, the global information cannot be fully incorporated into decision making. Herein, we propose an efficient and effective slide-level classification model, named as FALFormer, that can process a WSI as a whole so as to fully exploit the relationship among the entire patches and to improve the classification performance. FALFormer is built based upon Transformers and self-attention mechanism. To lessen the computational burden of the original self-attention mechanism and to process the entire patches together in a WSI, FALFormer employs Nystrom self-attention which approximates the computation by using a smaller number of tokens or landmarks. For effective learning, FALFormer introduces feature-aware landmarks to enhance the representation power of the landmarks and the quality of the approximation. We systematically evaluate the performance of FALFormer using two public datasets, including CAMELYON16 and TCGA-BRCA. The experimental results demonstrate that FALFormer achieves superior performance on both datasets, outperforming the state-of-the-art methods for the slide-level classification. This suggests that FALFormer can facilitate an accurate and precise analysis of WSIs, potentially leading to improved diagnosis and prognosis on WSIs. - - - -This work was conducted under the supervision of Prof. Jin Tae Kwak during my master's degree. -Paper and code will be released soon! diff --git a/_news/announcement_prl.md b/_news/announcement_prl.md deleted file mode 100644 index d0cbc4e..0000000 --- a/_news/announcement_prl.md +++ /dev/null @@ -1,30 +0,0 @@ ---- -layout: post -title: One paper has been accepted by Pattern Recognition Letters (IF = 5.1) -date: 2023-09-26 00:00:00 -description: Congratulations!

I hope that in the future, I will have chance to continue to do research with Thinh. And I wish he will continue to develop himself, leverage all chances coming to him, to become an excellent student in the future! Huyen Nguyen also showed her effort and performed co-working ability pretty well, I also believe that she will achieve further achievements in the future. - -**P/s 2**: We all know that papers are just the results of researching period, and they are not that all, they are just some milestones.

Mỗi năm, tại các hội nghị lớn như CVPR, ICCV, ECCV, ICLR đều xuất hiện các công bố liên quan đến bài toán này. Nhận thấy phát hiện đối tượng là bài toán quan trọng và là nền tảng giúp phát triển các bài toán khác trong thực tế, nhóm sinh viên lựa chọn và thực hiện tìm hiểu về bài toán này. - -## Các nghiên cứu trước khi có Faster R-CNN - -Hiện nay, các phương pháp phát hiện đối tượng được phân thành 02 loại: 02 giai đoạn và 01 giai đoạn. Đối với 01 giai đoạn sẽ được chia thành 02 nhánh phương pháp khác: anchor-free và anchor-based. Tuy nhiên, trong nội dung tiểu luận này, nhóm sinh viên chỉ tìm hiểu về phương pháp Faster R-CNN, và phương pháp này thuộc nhóm phương pháp 02 giai đoạn. Trước khi Faster R-CNN ra đời, đã có sự xuất hiện của 02 phương pháp: R-CNN và Fast R-CNN, trong đó Fast R-CNN là một cải tiến vô cùng hiệu quả của R-CNN, và Faster R-CNN là một bước phát triển lớn từ Fast R-CNN. Để trình bày Faster R-CNN, nhóm sinh viên sẽ nói lại sơ qua về phương pháp R-CNN và Fast R-CNN. - -### R-CNN - -Vào thời điểm trước khi nhóm phương pháp R-CNN ra đời, các phương pháp phát hiện đối tượng thường dựa vào đặc điểm của ảnh như màu sắc, và các thuật toán sử dụng mang hơi hướng phân cụm. R-CNN ra đời đánh dấu kỷ nguyên sử dụng kỹ thuật học sâu cho bài toán phát hiện đối tượng. - -![](https://i.imgur.com/wxFZHHH.png) -Hình 1. Minh họa phương pháp R-CNN [1]. - -Phương pháp này có thể được mô tả đơn giản như sau: đầu tiên thuật toán **selective search** sẽ chọn ra khoảng $N$ vùng trên ảnh có khả năng cao chứa đối tượng. Thuật toán này chủ yếu dựa vào các đặc điểm bức ảnh như màu sắc. Trong bài báo gốc, các tác giả sử dụng $$N = 2000$$, tức sẽ có $$2000$$ vùng được đề xuất trên ảnh. Từ 2000 vùng này, ta sẽ tiến hành cắt ra từ ảnh gốc, và một mạng CNN sẽ được sử dụng để trích xuất đặc trưng của 2000 vùng ảnh này. Sau đó, từ lớp đặc trưng cuối cùng sẽ đi qua 1 lớp FC để tính toán một bộ offset $$(\delta x, \delta y, \delta w, \delta h)$$, trong đó $$(\delta x, \delta y)$$ là offset tọa độ tâm của đối tượng, $$(\delta w, \delta h)$$ là offset chiều rộng và chiều cao của đối tượng. Như vậy, mạng sẽ học cách bo sát đối tượng và phân lớp đối tượng từ N vùng truyền vào ban đầu. Đối tượng sẽ được phân lớp bằng thuật toán SVM (Support Vector Machine). - -> Q: offset là gì? - -> A: offset gọi là phần bù. Tức là ban đầu selective search chọn ra 2000 vùng. 2000 vùng này đều có tọa độ (x, y, w, h). Tuy nhiên nó chưa bo sát đối tượng, ta cần một nhánh FC học cách bo sát, nhưng ta không học ra tọa độ chính xác, mà từ tọa độ ở selective search ta căn chỉnh lại, đó gọi là offset. - -Vậy ở đây chúng ta thấy điều gì? R-CNN phải thực hiện trích xuất đặc trưng cho $$2000$$ vùng ảnh, như thế rất tốn thời gian. Cuộc sống luôn phải vận động và phát triển, do đó Fast R-CNN ra đời để khắc phục điểm yếu chí mạng này của R-CNN. - -### Fast R-CNN - -Về cơ bản, Fast R-CNN vẫn giữ ý tưởng 02 giai đoạn của R-CNN. Selective Search vẫn được sử dụng để tìm 2000 vùng có khả năng chứa đối tượng, tuy nhiên điểm khác biệt ở đây là Fast R-CNN **trích xuất đặc trưng ảnh trước**, sau đó mới sử dụng selective search để tìm ra 2000 vùng đặc trưng. Do đó, ta chỉ cần đưa 2000 vùng đặc trưng này để tiếp tục xử lý mà không cần rút trích lại. Điều này là một bước ngoặt, vì nó đã tăng tốc độ xử lý lên rất nhiều ($$\times 18.3$$) cho huấn luyện và $$\times 146$$ cho suy luận) nhưng vẫn giữ được độ chính xác. - -![](https://i.imgur.com/ZBggmRI.png) -Hình 2. Minh họa mô hình Fast R-CNN [2]. - -Một điều cải tiến khác, Fast R-CNN không dùng SVM để phân lớp đối tượng nữa, mà tác giả gắn vào mạng một đầu FC để phân lớp. Tức là bây giờ chúng ta có 02 lớp FC, 1 lớp FC để phân lớp đối tượng, 1 lớp FC còn lại để tính toán bộ offset để căn chỉnh tọa độ đối tượng lại cho chính xác (giống như bên R-CNN). - -Cùng xem lại bảng kết quả so sánh giữa R-CNN và Fast R-CNN. Có thể thấy - -![](https://i.imgur.com/IrW35vU.png) - -Hình 3. Kết quả so sánh giữa Fast R-CNN và R-CNN [2]. - -Hình 3 là hình chụp kết quả từ bài báo gốc của Fast R-CNN. Có thể thấy rằng Fast R-CNN có kết quả tương đương với R-CNN, nhưng tốc độ vượt trội hơn rất nhiều. Tuy nhiên ý tưởng sử dụng 1 lớp FC để phân lớp chỉ vượt trội ở việc phát hiện các đối tượng lớn (L), các loại đối tượng nhỏ (S), trung bình (M) có hiệu quả phát hiện tương đương như R-CNN. Tuy nhiên với tốc độ vượt trội thế này thì không có lý do gì phải dùng R-CNN nữa. - -Tuy nhiên, Fast R-CNN vẫn có điểm yếu chí mạng của nó. Đó là việc lựa chọn vùng đề xuất vẫn dựa vào thuật toán Selective Search. *Liệu có cách nào cải tiến chính xác hơn ở điểm này hay không? Một cách tiếp cận khác mà nó tự học để đề xuất luôn.* - -Trên đây nhóm sinh viên cung cấp một cái nhìn tương đối đầy đủ về hoàn cảnh ra đời của Faster R-CNN. Phần dưới đây nhóm sinh viên sẽ trình bày kỹ hơn về Faster R-CNN. - -## Faster R-CNN - -Khắc phục điểm yếu chí mạng của Fast R-CNN, Faster R-CNN ra đời với hai điểm nổi bật duy nhất: -- Mạng đề xuất khu vực (Regional Proposal Network), gọi tắt là RPN. Mạng này được huấn luyện để phát hiện các vùng trên ảnh khả năng cao chứa đối tượng. Nói một cách đơn giản, RPN sẽ thay thế Selective Search. -- Cơ chế chia sẻ trọng số giữa RPN và Fast R-CNN. - -Đơn giản dễ hiểu, Faster R-CNN là sự kết hợp của RPN và mạng Fast R-CNN đã trình bày ở phía trên. Sau đó các tác giả đã thử các cơ chế chia sẻ trọng số khác nhau để kết hợp hoàn hảo hai thứ này. Dưới đây chúng ta sẽ tìm hiểu kỹ về mạng đề xuất khu vực. Đáng chú ý, Faster R-CNN được công bố tại hội nghị NeurlPS, là một hội nghị có những công bố mang tính bước ngoặt. Vì lẽ đó, Faster R-CNN được coi là một bước ngoặt. Faster R-CNN không còn là một phương pháp, Faster R-CNN đã là một hệ tư tưởng khi nhắc về nhóm phương pháp 02 giai đoạn. Dưới đây nhóm sinh viên sẽ trình bày kỹ về mạng đề xuất khu vực, và cơ chế chia sẻ trọng số - những thứ làm nên thành công của Faster R-CNN. - -### Mạng đề xuất khu vực (Regional Proposal Network) - -Như đã nói, mạng đề xuất khu vực sẽ được dùng để đề xuất các vùng khả năng cao chứa đối tượng thay cho thuật toán Selective Search. Gọi nó là "mạng" vì nó có "học". Thế làm sao để chúng ta huấn luyện được mạng này? - -![](https://i.imgur.com/POeFrpv.png) - -Hình 4. Minh họa cách chọn mẫu của Faster R-CNN [3]. - -Để huấn luyện được mạng RPN, chúng ta cần tạo dữ liệu cho nó học, cơ chế này được gọi là chọn mẫu (sampling). Để giải thích về cơ chế này, dễ nhất các bạn đọc quan sát Hình 4. Từ đặc trưng của ảnh (conv feature map), sẽ có một cửa sổ trượt có kích thước $$N \times N$$ (sliding window) trượt qua một cách lần lượt. Tại mỗi lần trượt, nó sẽ tạo ra $$k$$ anchor box. - -> Q: khoan khoan, dừng lại khoảng chừng là 2 giây. Anchor box là gì vậy? -> A: anchor box là một khái niệm chỉ các "hộp neo" được định nghĩa trước, làm tiền đề cho các bước phía sau. Tại sao gọi là "hộp neo", vì nó sẽ tạm thời neo đậu, dựa vào các hộp neo đậu này mà bằng một cách nào đó chúng ta sẽ sử dụng nó để xác định đối tượng trên ảnh. Khái niệm này sẽ còn gặp lại ở các nhóm phương pháp 01 giai đoạn. - -$$k$$ anchor box có $$k$$ kích thước khác nhau, trong bài báo gốc, tác giả chọn $$k=9$$. Mỗi anchor box sẽ được gán 2 thứ: - -- Lớp nhị phân xác định nó có đối tượng hay không. Nếu anchor box đó được xác định là mẫu có chứa đối tượng, ta gán là $$1$$, ngược lại là $$0$$. -- Tọa độ của anchor box, bao gồm 04 phần tử $$(x, y, w, h)$$. - -Thế thì làm sao chúng ta xác định được liệu 1 anchor box có chứa đối tượng hay không? Câu trả lời đơn giản là ta đi so với mẫu dữ liệu thật. Mỗi 1 anchor box sẽ được đi tính toán độ đo IoU với các hộp dự đoán thật (ground-truth), sau đó ta sẽ lấy giá trị IoU cao nhất của anchor box đó so với các ground-truth. Anchor box đó sẽ được chọn là mẫu $$1$$ khi $$IoU > 0.7$$, và chọn là mẫu $$0$$ khi $$IoU \leq 0.3$$. Vậy còn một đoạn từ $$(0.3, 0.7]$$ ta sẽ không chọn. - -Như vậy, bây giờ ta đã có một tập dữ liệu bao gồm các anchor box có đối tượng và anchor box không đối tượng cho mạng RPN học. - -Để huấn luyện ta cần định nghĩa một hàm mất mát tối ưu hóa đa mục tiêu: 1) xác định có hoặc không chứa đối tượng (phân lớp nhị phân); 2) hồi quy tọa độ. Hàm mất mát để huấn luyện RPN được định nghĩa như sau: - -$$L(\{p_i\}, \{t_i\}) = \frac{1}{N_{cls}} \sum_i L_{cls} (p_i, \hat p_i) + \lambda \frac{1}{N_{reg}} \sum_i \hat p_i L_{reg}(t_i, \hat t_i)$$ - -Trong đó, $$L_{cls}$$ là hàm binary cross-entropy, còn $$L_{reg}$$ là hàm mất mát hồi quy $$SmoothL1$$; $$\hat p_i$$ là phân phối xác suất dự đoán hộp đề xuất có đối tượng hay không, $$p_i$$ là nhãn thật sự; $$\hat t_i$$ là tọa độ dự đoán đã được tham số hóa; $$t_i$$ là tọa độ thật đã được tham số hóa, $$t=\{t_x, t_y, t_w, t_h\}$$ và $$\hat t=\{\hat t_x, \hat t_y, \hat t_w, \hat t_h\}$$ được định nghĩa như sau: - -$$ t_x = (x - x_a) / w_a; \hat t_x = (\hat x - x_a) / w_a $$ -$$ t_y = (y - y_a) / h_a; \hat t_y = (\hat y - y_a) / h_a $$ -$$ t_w = \log (w / w_a); \hat t_w = \log (\hat w / w_a) $$ -$$ t_h = \log (h / h_a); \hat t_h = \log (\hat h / h_a) $$ - -Trong đó, $$x$$, $$\hat x$$, $$x_a$$ lần lượt là hoành độ tâm thật sự của hộp bao, hoành độ tâm dự đoán của hộp bao và hoành độ tâm anchor box. $$y$$, $$\hat y$$, $$y_a$$ là tung độ tâm. Như thế ta có thể thấy, ở đây RPN không cố gắng để dự đoán các vị trí giống như hộp mỏ neo (vì nếu thế thì sử dụng hộp mỏ neo luôn cần gì học nữa), mà nó sẽ cố gắng dự đoán các vùng đề xuất lân cận các anchor box, mà tại đó có nhiều hộp bao ground-truth. - -Thực tế, RPN sinh ra rất nhiều hộp đề xuất, trong khi chúng ta chỉ cần $$N=2000$$ hộp đề xuất. Có nhiều hộp đề xuất ban đầu bị chồng lấp lên nhau, lúc này tác giả sử dụng thuật toán non maximum suppression (NMS) với ngưỡng $$IoU=0.7$$ để loại đi các hộp đề xuất chồng lấp, chỉ giữ lại $$2000$$ hộp đề xuất để đưa vào Fast R-CNN huấn luyện. Tuy nhiên, khi huấn luyện thì $$N=2000$$, trong khi đó lúc đánh giá (test) thì $$N$$ là một con số khác (nhỏ hơn 2000). - -### Cơ chế chia sẻ trọng số giữa RPN và Fast R-CNN (Sharing Convolutional Features) - -Việc huấn luyện RPN và Fast R-CNN được thực hiện độc lập chứ không end-to-end. Lý do của việc này rất dễ hiểu: rất khó để huấn luyện hai thứ này cùng một lúc. Fast R-CNN cần có một cơ chế sinh mẫu cố định (sinh ra các hộp đề xuất) để học, và bản thân Fast R-CNN cũng có một hàm tối ưu hóa tương tự như RPN (tổng của hàm mất mát phân lớp đối tượng và hàm mất mát hồi quy, nhưng hàm mất mát ở Fast R-CNN dùng cho đa lớp). Do đó không biế rằng nếu cơ chế sinh mẫu liên tục thay đổi (liên tục cập nhật trọng số lại ở RPN) thì mạng hợp nhất này có hội tụ được hay không. Do đó, tác giả đã đề xuất một cơ chế huấn luyện chia sẻ trọng số gồm 4 bước sau đây: - -- Bước 1: Huấn luyện RPN trước -- Bước 2: Đóng băng trọng số ở RPN, sử dụng mạng RPN vừa học được sinh ra các vùng đề xuất cho mạng Fast R-CNN. -- Bước 3: Dùng trọng số vừa học được ở mạng Fast R-CNN làm trọng số khởi tạo của mạng RPN ở các lớp tích chập (RPN và Fast R-CNN chia sẻ trọng số ở một số lớp tích chập), và chỉ fine-tune các lớp tích chập của riêng FPN và 2 lớp FC. -- Bước 4: Đóng băng trọng số ở mạng RPN vừa học để sinh các mẫu cho Fast R-CNN, và chỉ fine-tune Fast R-CNN ở 2 lớp FC. - -### Kết quả so với Fast R-CNN - -![](https://i.imgur.com/cV1APRP.png) - -Hình 5. Kết quả so sánh giữa việc sử dụng RPN và thuật toán Selective Search [3]. - -Có thể thấy, việc sử dụng thuật toán Selective Search cho kết quả thấp hơn khi sử dụng RPN. Hơn nữa, tốc độ xử lý của Fast R-CNN sử dụng RPN (Faster R-CNN) cũng nhanh hơn sử dụng thuật toán Selective Search. Vừa tốt hơn vừa nhanh hơn, Faster R-CNN đã trở thành một "hệ tư tưởng". - -## Hướng dẫn huấn luyện thử Faster R-CNN - -Faster R-CNN khá khó để có thể code from scratch. Do đó, trong nội dung bài viết này, nhóm sinh viên hướng dẫn bạn đọc cách huấn luyện thử một mô hình Faster R-CNN thông qua toolbox MMDetection [4]. - -Lưu ý: source code được thực nghiệm trên Google Colab. - -Trong bài này, nhóm sinh viên sử dụng bộ dữ liệu UIT-VinaDeveS22 được cung cấp ở đây: https://github.com/nguyenvd-uit/uit-together-dataset/blob/main/UIT-VinaDeveS22.md - -UIT-VinaDeveS22 là bộ dữ liệu phát hiện phương tiện giao thông từ camera CCTV, các phương tiện trong bộ dữ liệu bao gồm: bicycle, motorcycle, car, van, truck, bus, fire truck. - -![](https://i.imgur.com/xZDJryF.png) -Hình 6.

Chuẩn bị dữ liệu - -Tải dữ liệu tại đây: https://drive.google.com/file/d/1NhsIWyPdqF2KDqPWU926eZwCLk0gtjnv/view?usp=sharing - -Ta có thể tải bằng lệnh sau: - -``` -!gdown --id 1NhsIWyPdqF2KDqPWU926eZwCLk0gtjnv -``` - -Sau khi tải, chúng ta giải nén dữ liệu bằng lệnh `unzip` - -``` -!unzip UIT-VinaDeveS22.zip -``` - -Bộ dữ liệu được tổ chức theo cấu trúc sau: - -``` -UIT-VinaDeveS22 -|__ images -|____ *.jpg -|__ outputtrain.json -|__ outputvalid.json -|__ outputtest.json -``` - -Thư mục `images` chứa toàn bộ ảnh của bộ dữ liệu. 3 file `ouputtrain.json`, `outputvalid.json` và `outputtest.json` là 3 file annotation đã được chuẩn bị theo định dạng MS-COCO ứng với 3 tập: train, valid, test. - -### 4. Chuẩn bị config - -Bước này khá quan trọng. Hiện tại MMDetection đã hỗ trợ cho chúng ta rất nhiều config của nhiều phương pháp SOTA cho phát hiện đối tượng hiện tại, lên tới vài chục phương pháp. Tuy nhiên, chúng ta chỉ sử dụng config dành cho Faster R-CNN. - -- Bước 4.1: Config trong MMDetection được thiết kế theo cơ chế kế thừa, tức là từ config chuẩn bị sẵn, chúng ta sẽ tinh chỉnh cho phù hợp với bộ dữ liệu của chúng ta. Đầu tiên ta cần xác định config cha mà chúng ta sẽ kế thừa - -```[python3] -cfg = Config.fromfile('configs/faster_rcnn/faster_rcnn_r101_fpn_1x_coco.py') -``` - -`faster_rcnn_r101_fpn_1x_coco.py` là file config của phương pháp Faster R-CNN, sử dụng kiến trúc CNN ResNet-101 để trích xuất đặc trưng ảnh (là các lớp conv chung của mạng RPN và Fast R-CNN). Trong đó có sử dụng FPN (một cơ chế multi-scale feature map, tức là thay vì qua mạng CNN chỉ có 1 đầu ra thì nó sẽ có nhiều đầu ra với các resolution khác nhau). - -- Bước 4.2: Ta cần định nghĩa lại dữ liệu. MMDetection hỗ trợ các bộ dữ liệu sẵn có như COCO, sử dụng bộ dữ liệu khác ta cần định nghĩa lại các lớp. Tuy nhiên do cấu trúc bộ dữ liệu cũng giống như COCO, ta chỉ kế thừa nó về chỉnh lại các lớp sao cho phù hợp: - -```[python3] -from mmdet.datasets.builder import DATASETS -from mmdet.datasets import CocoDataset - -@DATASETS.register_module() -class VinaDeveS22(CocoDataset): - CLASSES = ('bicycle', 'motorcycle', 'car', 'van', 'truck', 'bus', 'fire truck') -``` - -- Bước 4.3: ta đặt đường dẫn cho tập dữ liệu, bao gồm đường dẫn ảnh, annotation cho tập train, test, valid: - -```[python3] -# Đường dẫn dữ liệu -import os -data_root_dir = '/content/drive/MyDrive/BDL_UIT/UIT-VinaDeveS22/' - -# Chuẩn bị config - -cfg = Config.fromfile('configs/faster_rcnn/faster_rcnn_r101_fpn_1x_coco.py') - -# Modify dataset type and path -cfg.data_root = data_root_dir - -cfg.data.test.type = 'VinaDeveS22' -cfg.data.test.ann_file = os.path.join(data_root_dir, 'outputtest.json') -cfg.data.test.img_prefix = os.path.join(data_root_dir, 'images') - -cfg.data.train.type = 'VinaDeveS22' -cfg.data.train.ann_file = os.path.join(data_root_dir, 'outputtrain.json') -cfg.data.train.img_prefix = os.path.join(data_root_dir, 'images') - -cfg.data.val.type = 'VinaDeveS22' -cfg.data.val.ann_file = os.path.join(data_root_dir, 'outputvalid.json') -cfg.data.val.img_prefix = os.path.join(data_root_dir, 'images') -``` - -- Bước 4.4: Một số cấu hình khác như số epoch để save checkpoint 1 lần, learning rate, đường dẫn lưu checkpoint, số lớp cần classify của mô hình, ... - -```[python3] -# Một số cấu hình khác - -cfg.optimizer.lr = 0.02 / 8 -cfg.lr_config.warmup = None -cfg.log_config.interval = 500 - -# We can set the evaluation interval to reduce the evaluation times -cfg.evaluation.interval = 1 -# We can set the checkpoint saving interval to reduce the storage cost -cfg.checkpoint_config.interval = 3 - -# Set seed thus the results are more reproducible -cfg.seed = 0 -set_random_seed(0, deterministic=False) -cfg.gpu_ids = range(1) - -# Số class -cfg.model.roi_head.bbox_head.num_classes = 7 - -# Đường dẫn lưu checkpoints -cfg.work_dir = './checkpoints' -``` - -### 5.

When - * individual tokens are needed at a position, the lexer is called to pull out a - * token, which is then used. - * - * The parser has a property called "mode" indicating the mode that - * the parser is currently in. Currently it has to be one of "math" or - * "text", which denotes whether the current environment is a math-y - * one or a text-y one (e.g. inside \text). Currently, this serves to - * limit the functions which can be used in text mode. - * - * The main functions then return an object which contains the useful data that - * was parsed at its given point, and a new position at the end of the parsed - * data. The main functions can call each other and continue the parsing by - * using the returned position as a new starting point. - * - * There are also extra `.handle...` functions, which pull out some reused - * functionality into self-contained functions. - * - * The earlier functions return ParseNodes. - * The later functions (which are called deeper in the parse) sometimes return - * ParseFuncOrArgument, which contain a ParseNode as well as some data about - * whether the parsed object is a function which is missing some arguments, or a - * standalone object which can be used as an argument to another function. - */ - - /** - * An initial function (without its arguments), or an argument to a function. - * The `result` argument should be a ParseNode. - */ - function ParseFuncOrArgument(result, isFunction, token) { - this.result = result; - // Is this a function (i.e. is it something defined in functions.js)? - this.isFunction = isFunction; - this.token = token; - } /* eslint no-constant-condition:0 */ - - var Parser = function () { - function Parser(input, settings) { - (0, _classCallCheck3.default)(this, Parser); - - // Create a new macro expander (gullet) and (indirectly via that) also a - // new lexer (mouth) for this parser (stomach, in the language of TeX) - this.gullet = new _MacroExpander2.default(input, settings.macros); - // Use old \color behavior (same as LaTeX's \textcolor) if requested. - // We do this after the macros object has been copied by MacroExpander. - if (settings.colorIsTextColor) { - this.gullet.macros["\\color"] = "\\textcolor"; - } - // Store the settings for use in parsing - this.settings = settings; - // Count leftright depth (for \middle errors) - this.leftrightDepth = 0; - } - - /** - * Checks a result to make sure it has the right type, and throws an - * appropriate error otherwise. - * - * @param {boolean=} consume whether to consume the expected token, - * defaults to true - */ - - - (0, _createClass3.default)(Parser, [{ - key: "expect", - value: function expect(text, consume) { - if (this.nextToken.text !== text) { - throw new _ParseError2.default("Expected '" + text + "', got '" + this.nextToken.text + "'", this.nextToken); - } - if (consume !== false) { - this.consume(); - } - } - - /** - * Considers the current look ahead token as consumed, - * and fetches the one after that as the new look ahead. - */ - - }, { - key: "consume", - value: function consume() { - this.nextToken = this.gullet.get(this.mode === "math"); - } - }, { - key: "switchMode", - value: function switchMode(newMode) { - this.gullet.unget(this.nextToken); - this.mode = newMode; - this.consume(); - } - - /** - * Main parsing function, which parses an entire input. - * - * @return {?Array.} - */ - - }, { - key: "parse", - value: function parse() { - // Try to parse the input - this.mode = "math"; - this.consume(); - var parse = this.parseInput(); - return parse; - } - - /** - * Parses an entire input tree. - */ - - }, { - key: "parseInput", - value: function parseInput() { - // Parse an expression - var expression = this.parseExpression(false); - // If we succeeded, make sure there's an EOF at the end - this.expect("EOF", false); - return expression; - } - }, { - key: "parseExpression", - - - /** - * Parses an "expression", which is a list of atoms. - * - * @param {boolean} breakOnInfix Should the parsing stop when we hit infix - * nodes?

* - * Each declared function can have associated properties, which - * include the following: - * - * - numArgs: The number of arguments the function takes. - * If this is the only property, it can be passed as a number - * instead of an element of a properties object. - * - argTypes: (optional) An array corresponding to each argument of the - * function, giving the type of argument that should be parsed. Its - * length should be equal to `numArgs + numOptionalArgs`. Valid - * types: - * - "size": A size-like thing, such as "1em" or "5ex" - * - "color": An html color, like "#abc" or "blue" - * - "original": The same type as the environment that the - * function being parsed is in (e.g. used for the - * bodies of functions like \textcolor where the - * first argument is special and the second - * argument is parsed normally) - * Other possible types (probably shouldn't be used) - * - "text": Text-like (e.g. \text) - * - "math": Normal math - * If undefined, this will be treated as an appropriate length - * array of "original" strings - * - greediness: (optional) The greediness of the function to use ungrouped - * arguments. - * - * E.g. if you have an expression - * \sqrt \frac 1 2 - * since \frac has greediness=2 vs \sqrt's greediness=1, \frac - * will use the two arguments '1' and '2' as its two arguments, - * then that whole function will be used as the argument to - * \sqrt. On the other hand, the expressions - * \frac \frac 1 2 3 - * and - * \frac \sqrt 1 2 - * will fail because \frac and \frac have equal greediness - * and \sqrt has a lower greediness than \frac respectively. To - * make these parse, we would have to change them to: - * \frac {\frac 1 2} 3 - * and - * \frac {\sqrt 1} 2 - * - * The default value is `1` - * - allowedInText: (optional) Whether or not the function is allowed inside - * text mode (default false) - * - numOptionalArgs: (optional) The number of optional arguments the function - * should parse. If the optional arguments aren't found, - * `null` will be passed to the handler in their place. - * (default 0) - * - infix: (optional) Must be true if the function is an infix operator. - * - * The last argument is that implementation, the handler for the function(s). - * It is called to handle these functions and their arguments. - * It receives two arguments: - * - context contains information and references provided by the parser - * - args is an array of arguments obtained from TeX input - * The context contains the following properties: - * - funcName: the text (i.e. name) of the function, including \ - * - parser: the parser object - * - lexer: the lexer object - * - positions: the positions in the overall string of the function - * and the arguments. - * The latter three should only be used to produce error messages. - * - * The function should return an object with the following keys: - * - type: The type of element that this is. This is then used in - * buildHTML/buildMathML to determine which function - * should be called to build this node into a DOM node - * Any other data can be added to the object, which will be passed - * in to the function in buildHTML/buildMathML as `group.value`. - */ - - function defineFunction(names, props, handler) { - if (typeof names === "string") { - names = [names]; - } - if (typeof props === "number") { - props = { numArgs: props }; - } - // Set default values of functions - var data = { - numArgs: props.numArgs, - argTypes: props.argTypes, - greediness: props.greediness === undefined ? 1 : props.greediness, - allowedInText: !!props.allowedInText, - allowedInMath: props.allowedInMath, - numOptionalArgs: props.numOptionalArgs || 0, - infix: !!props.infix, - handler: handler - }; - for (var i = 0; i < names.length; ++i) { - module.exports[names[i]] = data; - } - } - - // Since the corresponding buildHTML/buildMathML function expects a - // list of elements, we normalize for different kinds of arguments - var ordargument = function ordargument(arg) { - if (arg.type === "ordgroup") { - return arg.value; - } else { - return [arg]; - } - }; - - // A normal square root - defineFunction("\\sqrt", { - numArgs: 1, - numOptionalArgs: 1 - }, function (context, args) { - var index = args[0]; - var body = args[1]; - return { - type: "sqrt", - body: body, - index: index - }; - }); - - // Non-mathy text, possibly in a font - var textFunctionStyles = { - "\\text": undefined, "\\textrm": "mathrm", "\\textsf": "mathsf", - "\\texttt": "mathtt", "\\textnormal": "mathrm", "\\textbf": "mathbf", - "\\textit": "textit" - }; - - defineFunction(["\\text", "\\textrm", "\\textsf", "\\texttt", "\\textnormal", "\\textbf", "\\textit"], { - numArgs: 1, - argTypes: ["text"], - greediness: 2, - allowedInText: true - }, function (context, args) { - var body = args[0]; - return { - type: "text", - body: ordargument(body), - style: textFunctionStyles[context.funcName] - }; - }); - - // A two-argument custom color - defineFunction("\\textcolor", { - numArgs: 2, - allowedInText: true, - greediness: 3, - argTypes: ["color", "original"] - }, function (context, args) { - var color = args[0]; - var body = args[1]; - return { - type: "color", - color: color.value, - value: ordargument(body) - }; - }); - - // \color is handled in Parser.js's parseImplicitGroup - defineFunction("\\color", { - numArgs: 1, - allowedInText: true, - greediness: 3, - argTypes: ["color"] - }, null); - - // An overline - defineFunction("\\overline", { - numArgs: 1 - }, function (context, args) { - var body = args[0]; - return { - type: "overline", - body: body - }; - }); - - // An underline - defineFunction("\\underline", { - numArgs: 1 - }, function (context, args) { - var body = args[0]; - return { - type: "underline", - body: body - }; - }); - - // A box of the width and height - defineFunction("\\rule", { - numArgs: 2, - numOptionalArgs: 1, - argTypes: ["size", "size", "size"] - }, function (context, args) { - var shift = args[0]; - var width = args[1]; - var height = args[2]; - return { - type: "rule", - shift: shift && shift.value, - width: width.value, - height: height.value - }; - }); - - // TODO: In TeX, \mkern only accepts mu-units, and \kern does not accept - // mu-units.

      Faster R-CNN - Phương pháp phát hiện đối tượng 02 giai đoạn và lịch sử

      July 8, 2023

      Lời dẫn

      Phát hiện đối tượng là một trong các bài toán cơ sở của lĩnh vực Thị giác máy tính, và hiện vẫn được nghiên cứu rất sôi nổi. Mỗi năm, tại các hội nghị lớn như CVPR, ICCV, ECCV, ICLR đều xuất hiện các công bố liên quan đến bài toán này. Nhận thấy phát hiện đối tượng là bài toán quan trọng và là nền tảng giúp phát triển các bài toán khác trong thực tế, nhóm sinh viên lựa chọn và thực hiện tìm hiểu về bài toán này.

      Các nghiên cứu trước khi có Faster R-CNN

      Hiện nay, các phương pháp phát hiện đối tượng được phân thành 02 loại: 02 giai đoạn và 01 giai đoạn. Đối với 01 giai đoạn sẽ được chia thành 02 nhánh phương pháp khác: anchor-free và anchor-based. Tuy nhiên, trong nội dung tiểu luận này, nhóm sinh viên chỉ tìm hiểu về phương pháp Faster R-CNN, và phương pháp này thuộc nhóm phương pháp 02 giai đoạn. Trước khi Faster R-CNN ra đời, đã có sự xuất hiện của 02 phương pháp: R-CNN và Fast R-CNN, trong đó Fast R-CNN là một cải tiến vô cùng hiệu quả của R-CNN, và Faster R-CNN là một bước phát triển lớn từ Fast R-CNN. Để trình bày Faster R-CNN, nhóm sinh viên sẽ nói lại sơ qua về phương pháp R-CNN và Fast R-CNN.

      R-CNN

      Vào thời điểm trước khi nhóm phương pháp R-CNN ra đời, các phương pháp phát hiện đối tượng thường dựa vào đặc điểm của ảnh như màu sắc, và các thuật toán sử dụng mang hơi hướng phân cụm. R-CNN ra đời đánh dấu kỷ nguyên sử dụng kỹ thuật học sâu cho bài toán phát hiện đối tượng.

      Hình 1. Minh họa phương pháp R-CNN [1].

      Phương pháp này có thể được mô tả đơn giản như sau: đầu tiên thuật toán selective search sẽ chọn ra khoảng $N$ vùng trên ảnh có khả năng cao chứa đối tượng. Thuật toán này chủ yếu dựa vào các đặc điểm bức ảnh như màu sắc. Trong bài báo gốc, các tác giả sử dụng \(N = 2000\), tức sẽ có \(2000\) vùng được đề xuất trên ảnh. Từ 2000 vùng này, ta sẽ tiến hành cắt ra từ ảnh gốc, và một mạng CNN sẽ được sử dụng để trích xuất đặc trưng của 2000 vùng ảnh này. Sau đó, từ lớp đặc trưng cuối cùng sẽ đi qua 1 lớp FC để tính toán một bộ offset \((\delta x, \delta y, \delta w, \delta h)\), trong đó \((\delta x, \delta y)\) là offset tọa độ tâm của đối tượng, \((\delta w, \delta h)\) là offset chiều rộng và chiều cao của đối tượng. Như vậy, mạng sẽ học cách bo sát đối tượng và phân lớp đối tượng từ N vùng truyền vào ban đầu. Đối tượng sẽ được phân lớp bằng thuật toán SVM (Support Vector Machine).

      Q: offset là gì?

      A: offset gọi là phần bù. Tức là ban đầu selective search chọn ra 2000 vùng. 2000 vùng này đều có tọa độ (x, y, w, h). Tuy nhiên nó chưa bo sát đối tượng, ta cần một nhánh FC học cách bo sát, nhưng ta không học ra tọa độ chính xác, mà từ tọa độ ở selective search ta căn chỉnh lại, đó gọi là offset.

      Vậy ở đây chúng ta thấy điều gì? R-CNN phải thực hiện trích xuất đặc trưng cho \(2000\) vùng ảnh, như thế rất tốn thời gian. Cuộc sống luôn phải vận động và phát triển, do đó Fast R-CNN ra đời để khắc phục điểm yếu chí mạng này của R-CNN.

      Fast R-CNN

      Về cơ bản, Fast R-CNN vẫn giữ ý tưởng 02 giai đoạn của R-CNN. Selective Search vẫn được sử dụng để tìm 2000 vùng có khả năng chứa đối tượng, tuy nhiên điểm khác biệt ở đây là Fast R-CNN trích xuất đặc trưng ảnh trước, sau đó mới sử dụng selective search để tìm ra 2000 vùng đặc trưng. Do đó, ta chỉ cần đưa 2000 vùng đặc trưng này để tiếp tục xử lý mà không cần rút trích lại. Điều này là một bước ngoặt, vì nó đã tăng tốc độ xử lý lên rất nhiều (\(\times 18.3\)) cho huấn luyện và \(\times 146\) cho suy luận) nhưng vẫn giữ được độ chính xác.

      Hình 2. Minh họa mô hình Fast R-CNN [2].

      Một điều cải tiến khác, Fast R-CNN không dùng SVM để phân lớp đối tượng nữa, mà tác giả gắn vào mạng một đầu FC để phân lớp. Tức là bây giờ chúng ta có 02 lớp FC, 1 lớp FC để phân lớp đối tượng, 1 lớp FC còn lại để tính toán bộ offset để căn chỉnh tọa độ đối tượng lại cho chính xác (giống như bên R-CNN).

      Cùng xem lại bảng kết quả so sánh giữa R-CNN và Fast R-CNN. Có thể thấy

      Hình 3. Kết quả so sánh giữa Fast R-CNN và R-CNN [2].

      Hình 3 là hình chụp kết quả từ bài báo gốc của Fast R-CNN. Có thể thấy rằng Fast R-CNN có kết quả tương đương với R-CNN, nhưng tốc độ vượt trội hơn rất nhiều. Tuy nhiên ý tưởng sử dụng 1 lớp FC để phân lớp chỉ vượt trội ở việc phát hiện các đối tượng lớn (L), các loại đối tượng nhỏ (S), trung bình (M) có hiệu quả phát hiện tương đương như R-CNN. Tuy nhiên với tốc độ vượt trội thế này thì không có lý do gì phải dùng R-CNN nữa.

      Tuy nhiên, Fast R-CNN vẫn có điểm yếu chí mạng của nó. Đó là việc lựa chọn vùng đề xuất vẫn dựa vào thuật toán Selective Search. Liệu có cách nào cải tiến chính xác hơn ở điểm này hay không? Một cách tiếp cận khác mà nó tự học để đề xuất luôn.

      Trên đây nhóm sinh viên cung cấp một cái nhìn tương đối đầy đủ về hoàn cảnh ra đời của Faster R-CNN. Phần dưới đây nhóm sinh viên sẽ trình bày kỹ hơn về Faster R-CNN.

      Faster R-CNN

      Khắc phục điểm yếu chí mạng của Fast R-CNN, Faster R-CNN ra đời với hai điểm nổi bật duy nhất:

      • Mạng đề xuất khu vực (Regional Proposal Network), gọi tắt là RPN. Mạng này được huấn luyện để phát hiện các vùng trên ảnh khả năng cao chứa đối tượng. Nói một cách đơn giản, RPN sẽ thay thế Selective Search.
      • Cơ chế chia sẻ trọng số giữa RPN và Fast R-CNN.

      Đơn giản dễ hiểu, Faster R-CNN là sự kết hợp của RPN và mạng Fast R-CNN đã trình bày ở phía trên. Sau đó các tác giả đã thử các cơ chế chia sẻ trọng số khác nhau để kết hợp hoàn hảo hai thứ này. Dưới đây chúng ta sẽ tìm hiểu kỹ về mạng đề xuất khu vực. Đáng chú ý, Faster R-CNN được công bố tại hội nghị NeurlPS, là một hội nghị có những công bố mang tính bước ngoặt. Vì lẽ đó, Faster R-CNN được coi là một bước ngoặt. Faster R-CNN không còn là một phương pháp, Faster R-CNN đã là một hệ tư tưởng khi nhắc về nhóm phương pháp 02 giai đoạn. Dưới đây nhóm sinh viên sẽ trình bày kỹ về mạng đề xuất khu vực, và cơ chế chia sẻ trọng số - những thứ làm nên thành công của Faster R-CNN.

      Mạng đề xuất khu vực (Regional Proposal Network)

      Như đã nói, mạng đề xuất khu vực sẽ được dùng để đề xuất các vùng khả năng cao chứa đối tượng thay cho thuật toán Selective Search. Gọi nó là “mạng” vì nó có “học”. Thế làm sao để chúng ta huấn luyện được mạng này?

      Hình 4. Minh họa cách chọn mẫu của Faster R-CNN [3].

      Để huấn luyện được mạng RPN, chúng ta cần tạo dữ liệu cho nó học, cơ chế này được gọi là chọn mẫu (sampling). Để giải thích về cơ chế này, dễ nhất các bạn đọc quan sát Hình 4. Từ đặc trưng của ảnh (conv feature map), sẽ có một cửa sổ trượt có kích thước \(N \times N\) (sliding window) trượt qua một cách lần lượt. Tại mỗi lần trượt, nó sẽ tạo ra \(k\) anchor box.

      Q: khoan khoan, dừng lại khoảng chừng là 2 giây. Anchor box là gì vậy? A: anchor box là một khái niệm chỉ các “hộp neo” được định nghĩa trước, làm tiền đề cho các bước phía sau. Tại sao gọi là “hộp neo”, vì nó sẽ tạm thời neo đậu, dựa vào các hộp neo đậu này mà bằng một cách nào đó chúng ta sẽ sử dụng nó để xác định đối tượng trên ảnh. Khái niệm này sẽ còn gặp lại ở các nhóm phương pháp 01 giai đoạn.

      \(k\) anchor box có \(k\) kích thước khác nhau, trong bài báo gốc, tác giả chọn \(k=9\). Mỗi anchor box sẽ được gán 2 thứ:

      • Lớp nhị phân xác định nó có đối tượng hay không. Nếu anchor box đó được xác định là mẫu có chứa đối tượng, ta gán là \(1\), ngược lại là \(0\).
      • Tọa độ của anchor box, bao gồm 04 phần tử \((x, y, w, h)\).

      Thế thì làm sao chúng ta xác định được liệu 1 anchor box có chứa đối tượng hay không? Câu trả lời đơn giản là ta đi so với mẫu dữ liệu thật. Mỗi 1 anchor box sẽ được đi tính toán độ đo IoU với các hộp dự đoán thật (ground-truth), sau đó ta sẽ lấy giá trị IoU cao nhất của anchor box đó so với các ground-truth. Anchor box đó sẽ được chọn là mẫu \(1\) khi \(IoU > 0.7\), và chọn là mẫu \(0\) khi \(IoU \leq 0.3\). Vậy còn một đoạn từ \((0.3, 0.7]\) ta sẽ không chọn.

      Như vậy, bây giờ ta đã có một tập dữ liệu bao gồm các anchor box có đối tượng và anchor box không đối tượng cho mạng RPN học.

      Để huấn luyện ta cần định nghĩa một hàm mất mát tối ưu hóa đa mục tiêu: 1) xác định có hoặc không chứa đối tượng (phân lớp nhị phân); 2) hồi quy tọa độ. Hàm mất mát để huấn luyện RPN được định nghĩa như sau:

      \[L(\{p_i\}, \{t_i\}) = \frac{1}{N_{cls}} \sum_i L_{cls} (p_i, \hat p_i) + \lambda \frac{1}{N_{reg}} \sum_i \hat p_i L_{reg}(t_i, \hat t_i)\]

      Trong đó, \(L_{cls}\) là hàm binary cross-entropy, còn \(L_{reg}\) là hàm mất mát hồi quy \(SmoothL1\); \(\hat p_i\) là phân phối xác suất dự đoán hộp đề xuất có đối tượng hay không, \(p_i\) là nhãn thật sự; \(\hat t_i\) là tọa độ dự đoán đã được tham số hóa; \(t_i\) là tọa độ thật đã được tham số hóa, \(t=\{t_x, t_y, t_w, t_h\}\) và \(\hat t=\{\hat t_x, \hat t_y, \hat t_w, \hat t_h\}\) được định nghĩa như sau:

      \(t_x = (x - x_a) / w_a; \hat t_x = (\hat x - x_a) / w_a\) \(t_y = (y - y_a) / h_a; \hat t_y = (\hat y - y_a) / h_a\) \(t_w = \log (w / w_a); \hat t_w = \log (\hat w / w_a)\) \(t_h = \log (h / h_a); \hat t_h = \log (\hat h / h_a)\)

      Trong đó, \(x\), \(\hat x\), \(x_a\) lần lượt là hoành độ tâm thật sự của hộp bao, hoành độ tâm dự đoán của hộp bao và hoành độ tâm anchor box. \(y\), \(\hat y\), \(y_a\) là tung độ tâm. Như thế ta có thể thấy, ở đây RPN không cố gắng để dự đoán các vị trí giống như hộp mỏ neo (vì nếu thế thì sử dụng hộp mỏ neo luôn cần gì học nữa), mà nó sẽ cố gắng dự đoán các vùng đề xuất lân cận các anchor box, mà tại đó có nhiều hộp bao ground-truth.

      Thực tế, RPN sinh ra rất nhiều hộp đề xuất, trong khi chúng ta chỉ cần \(N=2000\) hộp đề xuất. Có nhiều hộp đề xuất ban đầu bị chồng lấp lên nhau, lúc này tác giả sử dụng thuật toán non maximum suppression (NMS) với ngưỡng \(IoU=0.7\) để loại đi các hộp đề xuất chồng lấp, chỉ giữ lại \(2000\) hộp đề xuất để đưa vào Fast R-CNN huấn luyện. Tuy nhiên, khi huấn luyện thì \(N=2000\), trong khi đó lúc đánh giá (test) thì \(N\) là một con số khác (nhỏ hơn 2000).

      Cơ chế chia sẻ trọng số giữa RPN và Fast R-CNN (Sharing Convolutional Features)

      Việc huấn luyện RPN và Fast R-CNN được thực hiện độc lập chứ không end-to-end. Lý do của việc này rất dễ hiểu: rất khó để huấn luyện hai thứ này cùng một lúc. Fast R-CNN cần có một cơ chế sinh mẫu cố định (sinh ra các hộp đề xuất) để học, và bản thân Fast R-CNN cũng có một hàm tối ưu hóa tương tự như RPN (tổng của hàm mất mát phân lớp đối tượng và hàm mất mát hồi quy, nhưng hàm mất mát ở Fast R-CNN dùng cho đa lớp). Do đó không biế rằng nếu cơ chế sinh mẫu liên tục thay đổi (liên tục cập nhật trọng số lại ở RPN) thì mạng hợp nhất này có hội tụ được hay không. Do đó, tác giả đã đề xuất một cơ chế huấn luyện chia sẻ trọng số gồm 4 bước sau đây:

      • Bước 1: Huấn luyện RPN trước
      • Bước 2: Đóng băng trọng số ở RPN, sử dụng mạng RPN vừa học được sinh ra các vùng đề xuất cho mạng Fast R-CNN.
      • Bước 3: Dùng trọng số vừa học được ở mạng Fast R-CNN làm trọng số khởi tạo của mạng RPN ở các lớp tích chập (RPN và Fast R-CNN chia sẻ trọng số ở một số lớp tích chập), và chỉ fine-tune các lớp tích chập của riêng FPN và 2 lớp FC.
      • Bước 4: Đóng băng trọng số ở mạng RPN vừa học để sinh các mẫu cho Fast R-CNN, và chỉ fine-tune Fast R-CNN ở 2 lớp FC.

      Kết quả so với Fast R-CNN

      Hình 5. Kết quả so sánh giữa việc sử dụng RPN và thuật toán Selective Search [3].

      Có thể thấy, việc sử dụng thuật toán Selective Search cho kết quả thấp hơn khi sử dụng RPN. Hơn nữa, tốc độ xử lý của Fast R-CNN sử dụng RPN (Faster R-CNN) cũng nhanh hơn sử dụng thuật toán Selective Search. Vừa tốt hơn vừa nhanh hơn, Faster R-CNN đã trở thành một “hệ tư tưởng”.

      Hướng dẫn huấn luyện thử Faster R-CNN

      Faster R-CNN khá khó để có thể code from scratch. Do đó, trong nội dung bài viết này, nhóm sinh viên hướng dẫn bạn đọc cách huấn luyện thử một mô hình Faster R-CNN thông qua toolbox MMDetection [4].

      Lưu ý: source code được thực nghiệm trên Google Colab.

      Trong bài này, nhóm sinh viên sử dụng bộ dữ liệu UIT-VinaDeveS22 được cung cấp ở đây: https://github.com/nguyenvd-uit/uit-together-dataset/blob/main/UIT-VinaDeveS22.md

      UIT-VinaDeveS22 là bộ dữ liệu phát hiện phương tiện giao thông từ camera CCTV, các phương tiện trong bộ dữ liệu bao gồm: bicycle, motorcycle, car, van, truck, bus, fire truck.

      Hình 6. Hình ảnh bộ dữ liệu UIT-VinaDeveS22

      1. Cài đặt thư viện

      Đầu tiên, chúng ta cần clone toolbox MMDetection từ Github về, sau đó cài đặt các thư viện cần thiết:

      • Bước 1.1: git clone thư mục code 
        !git clone https://github.com/open-mmlab/mmdetection
+
      • Bước 1.2: cài đặt thư viện 
        # Cài đặt thư viện
+%cd mmdetection
+!pip install -r requirements.txt
+!pip install -v -e .
+!pip install mmcv-full==1.3.8 -f https://download.openmmlab.com/mmcv/dist/cu101/torch1.7.0/index.html
+!pip install torch==1.7.1 torchvision==0.8.2 torchaudio==0.7.2
+

      2. Import thư viện

      • Bước 2.1: ta import các thư viện liên quan cần dùng, ở đây chúng ta cần import mmdet, mmcv.
      # Dùng để build config
+import mmdet
+from mmdet.apis import set_random_seed
+from mmcv import Config
+
+# Dùng để xây dựng dataset
+from mmdet.datasets import build_dataset
+from mmdet.models import build_detector
+from mmdet.apis import train_detector
+
+# Dùng để dự đoán
+from mmdet.apis import init_detector, inference_detector, show_result_pyplot
+import mmcv
+

      3. Chuẩn bị dữ liệu

      Tải dữ liệu tại đây: https://drive.google.com/file/d/1NhsIWyPdqF2KDqPWU926eZwCLk0gtjnv/view?usp=sharing

      Ta có thể tải bằng lệnh sau:

      !gdown --id 1NhsIWyPdqF2KDqPWU926eZwCLk0gtjnv
+

      Sau khi tải, chúng ta giải nén dữ liệu bằng lệnh unzip

      !unzip UIT-VinaDeveS22.zip
+

      Bộ dữ liệu được tổ chức theo cấu trúc sau:

      UIT-VinaDeveS22
+|__ images
+|____ *.jpg
+|__ outputtrain.json
+|__ outputvalid.json
+|__ outputtest.json
+

      Thư mục images chứa toàn bộ ảnh của bộ dữ liệu. 3 file ouputtrain.json, outputvalid.json và outputtest.json là 3 file annotation đã được chuẩn bị theo định dạng MS-COCO ứng với 3 tập: train, valid, test.

      4. Chuẩn bị config

      Bước này khá quan trọng. Hiện tại MMDetection đã hỗ trợ cho chúng ta rất nhiều config của nhiều phương pháp SOTA cho phát hiện đối tượng hiện tại, lên tới vài chục phương pháp. Tuy nhiên, chúng ta chỉ sử dụng config dành cho Faster R-CNN.

      • Bước 4.1: Config trong MMDetection được thiết kế theo cơ chế kế thừa, tức là từ config chuẩn bị sẵn, chúng ta sẽ tinh chỉnh cho phù hợp với bộ dữ liệu của chúng ta. Đầu tiên ta cần xác định config cha mà chúng ta sẽ kế thừa
      cfg = Config.fromfile('configs/faster_rcnn/faster_rcnn_r101_fpn_1x_coco.py')
+

      faster_rcnn_r101_fpn_1x_coco.py là file config của phương pháp Faster R-CNN, sử dụng kiến trúc CNN ResNet-101 để trích xuất đặc trưng ảnh (là các lớp conv chung của mạng RPN và Fast R-CNN). Trong đó có sử dụng FPN (một cơ chế multi-scale feature map, tức là thay vì qua mạng CNN chỉ có 1 đầu ra thì nó sẽ có nhiều đầu ra với các resolution khác nhau).

      • Bước 4.2: Ta cần định nghĩa lại dữ liệu. MMDetection hỗ trợ các bộ dữ liệu sẵn có như COCO, sử dụng bộ dữ liệu khác ta cần định nghĩa lại các lớp. Tuy nhiên do cấu trúc bộ dữ liệu cũng giống như COCO, ta chỉ kế thừa nó về chỉnh lại các lớp sao cho phù hợp:
      from mmdet.datasets.builder import DATASETS
+from mmdet.datasets import CocoDataset
+
+@DATASETS.register_module()
+class VinaDeveS22(CocoDataset):
+    CLASSES = ('bicycle', 'motorcycle', 'car', 'van', 'truck', 'bus', 'fire truck')
+
      • Bước 4.3: ta đặt đường dẫn cho tập dữ liệu, bao gồm đường dẫn ảnh, annotation cho tập train, test, valid:
      # Đường dẫn dữ liệu
+import os
+data_root_dir = '/content/drive/MyDrive/BDL_UIT/UIT-VinaDeveS22/'
+
+# Chuẩn bị config
+
+cfg = Config.fromfile('configs/faster_rcnn/faster_rcnn_r101_fpn_1x_coco.py')
+
+# Modify dataset type and path
+cfg.data_root = data_root_dir
+
+cfg.data.test.type = 'VinaDeveS22'
+cfg.data.test.ann_file = os.path.join(data_root_dir, 'outputtest.json')
+cfg.data.test.img_prefix = os.path.join(data_root_dir, 'images')
+
+cfg.data.train.type = 'VinaDeveS22'
+cfg.data.train.ann_file = os.path.join(data_root_dir, 'outputtrain.json')
+cfg.data.train.img_prefix = os.path.join(data_root_dir, 'images')
+
+cfg.data.val.type = 'VinaDeveS22'
+cfg.data.val.ann_file = os.path.join(data_root_dir, 'outputvalid.json')
+cfg.data.val.img_prefix = os.path.join(data_root_dir, 'images')
+
      • Bước 4.4: Một số cấu hình khác như số epoch để save checkpoint 1 lần, learning rate, đường dẫn lưu checkpoint, số lớp cần classify của mô hình, …
      # Một số cấu hình khác
+
+cfg.optimizer.lr = 0.02 / 8
+cfg.lr_config.warmup = None
+cfg.log_config.interval = 500
+
+# We can set the evaluation interval to reduce the evaluation times
+cfg.evaluation.interval = 1
+# We can set the checkpoint saving interval to reduce the storage cost
+cfg.checkpoint_config.interval = 3
+
+# Set seed thus the results are more reproducible
+cfg.seed = 0
+set_random_seed(0, deterministic=False)
+cfg.gpu_ids = range(1)
+
+# Số class
+cfg.model.roi_head.bbox_head.num_classes = 7
+
+# Đường dẫn lưu checkpoints
+cfg.work_dir = './checkpoints'
+

      5. Xây dựng model và huấn luyện

      Ta tiến hành xây dựng mô hình dựa trên config đã chuẩn bị:

      # Build dataset
+datasets = [build_dataset(cfg.data.train)]
+
+# Build the detector
+model = build_detector(cfg.model, train_cfg=cfg.get('train_cfg'), test_cfg=cfg.get('test_cfg'))
+# Add an attribute for visualization convenience
+model.CLASSES = ('bicycle', 'motorcycle', 'car', 'van', 'truck', 'bus', 'fire truck')
+

      Tiến hành huấn luyện:

      train_detector(model, datasets, cfg, distributed=False, validate=True)
+

      Log khi huấn luyện:

      Bước 6: Dự đoán trên ảnh mới

      Sau khi huấn luyện xong, ta thử dự đoán trên 01 ảnh mới. Giả sử nhóm sinh viên chọn ảnh 000000100.jpg trong tập dữ liệu:

      # Show thử 1 vài ảnh
+img = mmcv.imread('/content/drive/MyDrive/BDL_UIT/UIT-VinaDeveS22/images/000000100.jpg')
+
+model.cfg = cfg
+result = inference_detector(model, img)
+show_result_pyplot(model, img, result)
+

      Hình ảnh đầu ra:

      Kính chào quý bằng hữu,

      Tại hạ là Doanh (Công Danh), xin phép được gửi đến quý bằng hữu, những người cùng sở thích thi ca một tập thơ mà tại hạ đã sáng tác trong quá trình làm việc và sinh sống tại Thủ Nhĩ, Đại Hàn.

      Trong tập thơ này, tại hạ giới thiệu một số bài thơ mà tại hạ viết ở thể 5 chữ, hoặc 7 chữ, hoặc thơ 6-8. Tại hạ đặc biệt thích thể loại thơ 7 chữ, theo luật Đại Đường (thất ngôn tứ tuyệt Đường luật).

      Các bài thơ tại hạ viết chủ yếu có chủ đề về nhân sinh và tình yêu, và hầu hết được sáng tác vào lúc 1-2 giờ sáng, lúc mà tâm trạng dâng trào nhất. Về chủ đề nhân sinh, tại hạ thường viết về góc nhìn của mình về cuộc đời với tâm trạng hơi u tối một chút, nhưng đâu đó vẫn có màu tươi sáng. Về tình yêu, tại hạ thường viết về chủ đề mối tình đã lỡ. Câu cú có phần một chút trách móc, nhưng tiếc thương một mối tình đã lỡ, và da diết tôn trọng.

      Các bài thơ sẽ có các lỗi trong cách gieo vần, dùng từ. Nếu đọc thơ khiến các bằng hữu không thoải mái, tại hạ rất xin lỗi, và luôn đó nhận những lời góp ý.

      Mời quý bằng hữu thưởng thơ.

      Kính bút,

      Công Danh

      Lập Thu Đại Hàn

      Lập thu nơi xóm nhỏ

      Cho nỗi niềm chơi vơi

      Đôi điều còn bỏ ngõ

      Tìm đâu phía chân trời.

      Công Danh, 6.9.2023

      Cầu vồng tình lỡ

      Cầu vồng đẹp nhất sau mưa

      Ngày em đẹp nhất là vừa xa anh

      Buồn nào rồi cũng trôi nhanh

      Nhưng thành vết xẹo khó lành về sau

      Công Danh, 11.9.2023

      Miền đất khác

      Một vệt nắng cuối trời

      Cho chiều buồn man mác

      Liệu một miền đất khác

      Có nỗi niềm chơi vơi?

      Công Danh, 12.9.2023

      Lửa thủ đô

      Bài thơ tỏ lòng tiếc thương cho các nạn nhân của một vụ cháy kinh hoàng ở thủ đô Hà Nội

      Ở giữa lòng thủ đô

      Một màu buồn man mác

      Trời đêm mưa lác đác

      Lửa hóa kiếp hư vô…

      Công Danh, 14.9.2023

      Tình tan

      Đượm nắng lập thu cuối chiều ta

      Niệm về ngày cũ vốn phôi pha

      Hoàng hôn chớm tắt, hồn vô ngã

      Chôn giấu tình tan, em với ta.

      Ánh mắt ai đậm đà

      Tiếng cười ai giòn giã,

      Tâm tư ai la cà

      Không phải em, là lá…

      Công Danh và Minh Niên, 20.9.2023

      Hạnh phúc mới

      Bài thơ được sáng tác từ bài hát Hạnh phúc mới, nhưng đổi vai hai nhân vật nam và nữ.

      Ngày hôm nào em nói

      Mình chia tay thôi anh

      Nghe như lời trăn trối

      Gạt lệ buồn phai nhanh.

      Anh à, đừng buồn nữa

      Tình nào cũng thế thôi

      Hợp, yêu, tan, rồi mất

      Còn nỗi lòng đơn côi.

      Em đang ở đâu đó

      Để nỗi niềm chơi vơi

      Hồn em bay theo gió

      Tìm em cuối chân trời…

      Công Danh, 8.10.2023

      Sài Gòn nhỏ

      Bài thơ được sáng tác rất lâu, nhưng đến ngày này mới hoàn chỉnh

      Có một Sài Gòn nhỏ

      Con phố đông người qua

      Có chuyến xe buýt nọ

      Từng chở cuộc tình ta.

      Ngày đôi mình chia xa,

      Hạ vẫn còn vương nắng

      Tình ngọt chợt thành đắng

      Chỉ còn dằm trong tim.

      Đôi mắt anh lim dim

      Mơ về ngày ngây dại

      Thấy em quay nhìn lại

      Như tình mình chưa phai.

      Công Danh, 12.10.2023

      Cầu sông Hậu

      Nhớ về ngày cũ còn đâu,

      Bóng hình em gái hát câu gọi đò

      Ngân vang sông Hậu câu hò

      Giờ đây chẳng phải đi đò sang ngang

      Ai về Châu Đốc, An Giang,

      Qua cậu sông Hậu, gửi nàng yêu thương.

      Công Danh, 11.11.2023

      Một kiếp người

      Bài thơ sáng tác để tiếc thương cho một người bà của một người bạn đã mất.

      Thoáng chốc là xong một kiếp người

      Hồng trần vướng bận cứ buông lơi

      Người đi về chốn hồn thanh thản

      Để lại ngàn năm nỗi đau đời.

      Các bản dịch bài thơ nổi tiếng của William Shakespeare

      Ở phần này, tại hạ giới thiệu các bằng hữu bản dịch do tại hạ thực hiện cho một bài thơ nổi tiếng dưới phong cách của các nhà thơ lớn của thi văn Việt Nam.

      Bản gốc:

      You say that you love rain, but you open your umbrella when it rains.

      You say that you love the sun, but you find a shadow spot when the sun shines.

      You say that you love the wind, but you close your windows when wind blows.

      This is why I am afraid, you say that you love me too

      Bản dịch phong cách Xuân Diệu:

      Em nói rất thích mưa

      Sao tìm dù mà tránh

      Em thích nhìn nắng hạ

      Sao đi tìm nơi râm.

      Em từng nói rằng em yêu gió lộng

      Vậy mà sao giờ chốt cửa cài then

      Chợt thổn thức, anh thẹn cười bẽn lẽn

      Thế thì còn… lời em nói yêu anh?

      Bản dịch phong cách Hàn Mặc Tử:

      Sao em không còn yêu mưa nhỉ?

      Mà kéo dù lên tránh ướt mi

      Rồi kêu thích nắng, yêu hương Hạ

      Thế núp nơi râm là nghĩa gì?

      Em nói rằng yêu, gió vừa qua

      Thế sao cửa đóng, rèm bung ra?

      Bỗng nhiên anh thấy thật không ổn

      Ai biết tình em có đậm đà…

      Bản dịch phong cách Tố Hữu:

      Từng nói yêu mưa, giờ khác lạ

      Rồi chợt mưa đến lấy ô ra

      Và em từng thì thầm yêu nắng

      Nắng rọi lên thì chẳng thiết tha.

      Bản dịch phong cách Nguyễn Thị Hinh (Bà Huyện Thanh Quan):

      Nhớ nói trời mưa thích thế mà

      Chẳng mưa to mấy lấy ô ra

      Sao em muốn ngắm trời hừng nắng

      Nắng rọi lên cao lại núp nhà

      Ngắm gió mây làm em thích thích

      Bây giờ chốt cửa tránh xa xa

      Chợt sao thấy lạ lời em nói

      Thật giả tình yêu, em với ta.

      ]]>      Faster R-CNN - Phương pháp phát hiện đối tượng 02 giai đoạn và lịch sử2023-07-08T13:50:00+00:002023-07-08T13:50:00+00:00https://caodoanh2001.github.io/blog/2023/faster-rcnnLời dẫn

      Phát hiện đối tượng là một trong các bài toán cơ sở của lĩnh vực Thị giác máy tính, và hiện vẫn được nghiên cứu rất sôi nổi. Mỗi năm, tại các hội nghị lớn như CVPR, ICCV, ECCV, ICLR đều xuất hiện các công bố liên quan đến bài toán này. Nhận thấy phát hiện đối tượng là bài toán quan trọng và là nền tảng giúp phát triển các bài toán khác trong thực tế, nhóm sinh viên lựa chọn và thực hiện tìm hiểu về bài toán này.

      Các nghiên cứu trước khi có Faster R-CNN

      Hiện nay, các phương pháp phát hiện đối tượng được phân thành 02 loại: 02 giai đoạn và 01 giai đoạn. Đối với 01 giai đoạn sẽ được chia thành 02 nhánh phương pháp khác: anchor-free và anchor-based. Tuy nhiên, trong nội dung tiểu luận này, nhóm sinh viên chỉ tìm hiểu về phương pháp Faster R-CNN, và phương pháp này thuộc nhóm phương pháp 02 giai đoạn. Trước khi Faster R-CNN ra đời, đã có sự xuất hiện của 02 phương pháp: R-CNN và Fast R-CNN, trong đó Fast R-CNN là một cải tiến vô cùng hiệu quả của R-CNN, và Faster R-CNN là một bước phát triển lớn từ Fast R-CNN. Để trình bày Faster R-CNN, nhóm sinh viên sẽ nói lại sơ qua về phương pháp R-CNN và Fast R-CNN.

      R-CNN

      Vào thời điểm trước khi nhóm phương pháp R-CNN ra đời, các phương pháp phát hiện đối tượng thường dựa vào đặc điểm của ảnh như màu sắc, và các thuật toán sử dụng mang hơi hướng phân cụm. R-CNN ra đời đánh dấu kỷ nguyên sử dụng kỹ thuật học sâu cho bài toán phát hiện đối tượng.

      Hình 1. Minh họa phương pháp R-CNN [1].

      Phương pháp này có thể được mô tả đơn giản như sau: đầu tiên thuật toán selective search sẽ chọn ra khoảng $N$ vùng trên ảnh có khả năng cao chứa đối tượng. Thuật toán này chủ yếu dựa vào các đặc điểm bức ảnh như màu sắc. Trong bài báo gốc, các tác giả sử dụng \(N = 2000\), tức sẽ có \(2000\) vùng được đề xuất trên ảnh. Từ 2000 vùng này, ta sẽ tiến hành cắt ra từ ảnh gốc, và một mạng CNN sẽ được sử dụng để trích xuất đặc trưng của 2000 vùng ảnh này. Sau đó, từ lớp đặc trưng cuối cùng sẽ đi qua 1 lớp FC để tính toán một bộ offset \((\delta x, \delta y, \delta w, \delta h)\), trong đó \((\delta x, \delta y)\) là offset tọa độ tâm của đối tượng, \((\delta w, \delta h)\) là offset chiều rộng và chiều cao của đối tượng. Như vậy, mạng sẽ học cách bo sát đối tượng và phân lớp đối tượng từ N vùng truyền vào ban đầu. Đối tượng sẽ được phân lớp bằng thuật toán SVM (Support Vector Machine).

      Q: offset là gì?

      A: offset gọi là phần bù. Tức là ban đầu selective search chọn ra 2000 vùng. 2000 vùng này đều có tọa độ (x, y, w, h). Tuy nhiên nó chưa bo sát đối tượng, ta cần một nhánh FC học cách bo sát, nhưng ta không học ra tọa độ chính xác, mà từ tọa độ ở selective search ta căn chỉnh lại, đó gọi là offset.

      Vậy ở đây chúng ta thấy điều gì? R-CNN phải thực hiện trích xuất đặc trưng cho \(2000\) vùng ảnh, như thế rất tốn thời gian. Cuộc sống luôn phải vận động và phát triển, do đó Fast R-CNN ra đời để khắc phục điểm yếu chí mạng này của R-CNN.

      Fast R-CNN

      Về cơ bản, Fast R-CNN vẫn giữ ý tưởng 02 giai đoạn của R-CNN. Selective Search vẫn được sử dụng để tìm 2000 vùng có khả năng chứa đối tượng, tuy nhiên điểm khác biệt ở đây là Fast R-CNN trích xuất đặc trưng ảnh trước, sau đó mới sử dụng selective search để tìm ra 2000 vùng đặc trưng. Do đó, ta chỉ cần đưa 2000 vùng đặc trưng này để tiếp tục xử lý mà không cần rút trích lại. Điều này là một bước ngoặt, vì nó đã tăng tốc độ xử lý lên rất nhiều (\(\times 18.3\)) cho huấn luyện và \(\times 146\) cho suy luận) nhưng vẫn giữ được độ chính xác.

      Hình 2. Minh họa mô hình Fast R-CNN [2].

      Một điều cải tiến khác, Fast R-CNN không dùng SVM để phân lớp đối tượng nữa, mà tác giả gắn vào mạng một đầu FC để phân lớp. Tức là bây giờ chúng ta có 02 lớp FC, 1 lớp FC để phân lớp đối tượng, 1 lớp FC còn lại để tính toán bộ offset để căn chỉnh tọa độ đối tượng lại cho chính xác (giống như bên R-CNN).

      Cùng xem lại bảng kết quả so sánh giữa R-CNN và Fast R-CNN. Có thể thấy

      Hình 3. Kết quả so sánh giữa Fast R-CNN và R-CNN [2].

      Hình 3 là hình chụp kết quả từ bài báo gốc của Fast R-CNN. Có thể thấy rằng Fast R-CNN có kết quả tương đương với R-CNN, nhưng tốc độ vượt trội hơn rất nhiều. Tuy nhiên ý tưởng sử dụng 1 lớp FC để phân lớp chỉ vượt trội ở việc phát hiện các đối tượng lớn (L), các loại đối tượng nhỏ (S), trung bình (M) có hiệu quả phát hiện tương đương như R-CNN. Tuy nhiên với tốc độ vượt trội thế này thì không có lý do gì phải dùng R-CNN nữa.

      Tuy nhiên, Fast R-CNN vẫn có điểm yếu chí mạng của nó. Đó là việc lựa chọn vùng đề xuất vẫn dựa vào thuật toán Selective Search. Liệu có cách nào cải tiến chính xác hơn ở điểm này hay không? Một cách tiếp cận khác mà nó tự học để đề xuất luôn.

      Trên đây nhóm sinh viên cung cấp một cái nhìn tương đối đầy đủ về hoàn cảnh ra đời của Faster R-CNN. Phần dưới đây nhóm sinh viên sẽ trình bày kỹ hơn về Faster R-CNN.

      Faster R-CNN

      Khắc phục điểm yếu chí mạng của Fast R-CNN, Faster R-CNN ra đời với hai điểm nổi bật duy nhất:

      • Mạng đề xuất khu vực (Regional Proposal Network), gọi tắt là RPN. Mạng này được huấn luyện để phát hiện các vùng trên ảnh khả năng cao chứa đối tượng. Nói một cách đơn giản, RPN sẽ thay thế Selective Search.
      • Cơ chế chia sẻ trọng số giữa RPN và Fast R-CNN.

      Đơn giản dễ hiểu, Faster R-CNN là sự kết hợp của RPN và mạng Fast R-CNN đã trình bày ở phía trên. Sau đó các tác giả đã thử các cơ chế chia sẻ trọng số khác nhau để kết hợp hoàn hảo hai thứ này. Dưới đây chúng ta sẽ tìm hiểu kỹ về mạng đề xuất khu vực. Đáng chú ý, Faster R-CNN được công bố tại hội nghị NeurlPS, là một hội nghị có những công bố mang tính bước ngoặt. Vì lẽ đó, Faster R-CNN được coi là một bước ngoặt. Faster R-CNN không còn là một phương pháp, Faster R-CNN đã là một hệ tư tưởng khi nhắc về nhóm phương pháp 02 giai đoạn. Dưới đây nhóm sinh viên sẽ trình bày kỹ về mạng đề xuất khu vực, và cơ chế chia sẻ trọng số - những thứ làm nên thành công của Faster R-CNN.

      Mạng đề xuất khu vực (Regional Proposal Network)

      Như đã nói, mạng đề xuất khu vực sẽ được dùng để đề xuất các vùng khả năng cao chứa đối tượng thay cho thuật toán Selective Search. Gọi nó là “mạng” vì nó có “học”. Thế làm sao để chúng ta huấn luyện được mạng này?

      Hình 4. Minh họa cách chọn mẫu của Faster R-CNN [3].

      Để huấn luyện được mạng RPN, chúng ta cần tạo dữ liệu cho nó học, cơ chế này được gọi là chọn mẫu (sampling). Để giải thích về cơ chế này, dễ nhất các bạn đọc quan sát Hình 4. Từ đặc trưng của ảnh (conv feature map), sẽ có một cửa sổ trượt có kích thước \(N \times N\) (sliding window) trượt qua một cách lần lượt. Tại mỗi lần trượt, nó sẽ tạo ra \(k\) anchor box.

      Q: khoan khoan, dừng lại khoảng chừng là 2 giây. Anchor box là gì vậy? A: anchor box là một khái niệm chỉ các “hộp neo” được định nghĩa trước, làm tiền đề cho các bước phía sau. Tại sao gọi là “hộp neo”, vì nó sẽ tạm thời neo đậu, dựa vào các hộp neo đậu này mà bằng một cách nào đó chúng ta sẽ sử dụng nó để xác định đối tượng trên ảnh. Khái niệm này sẽ còn gặp lại ở các nhóm phương pháp 01 giai đoạn.

      \(k\) anchor box có \(k\) kích thước khác nhau, trong bài báo gốc, tác giả chọn \(k=9\). Mỗi anchor box sẽ được gán 2 thứ:

      • Lớp nhị phân xác định nó có đối tượng hay không. Nếu anchor box đó được xác định là mẫu có chứa đối tượng, ta gán là \(1\), ngược lại là \(0\).
      • Tọa độ của anchor box, bao gồm 04 phần tử \((x, y, w, h)\).

      Thế thì làm sao chúng ta xác định được liệu 1 anchor box có chứa đối tượng hay không? Câu trả lời đơn giản là ta đi so với mẫu dữ liệu thật. Mỗi 1 anchor box sẽ được đi tính toán độ đo IoU với các hộp dự đoán thật (ground-truth), sau đó ta sẽ lấy giá trị IoU cao nhất của anchor box đó so với các ground-truth. Anchor box đó sẽ được chọn là mẫu \(1\) khi \(IoU > 0.7\), và chọn là mẫu \(0\) khi \(IoU \leq 0.3\). Vậy còn một đoạn từ \((0.3, 0.7]\) ta sẽ không chọn.

      Như vậy, bây giờ ta đã có một tập dữ liệu bao gồm các anchor box có đối tượng và anchor box không đối tượng cho mạng RPN học.

      Để huấn luyện ta cần định nghĩa một hàm mất mát tối ưu hóa đa mục tiêu: 1) xác định có hoặc không chứa đối tượng (phân lớp nhị phân); 2) hồi quy tọa độ. Hàm mất mát để huấn luyện RPN được định nghĩa như sau:

      \[L(\{p_i\}, \{t_i\}) = \frac{1}{N_{cls}} \sum_i L_{cls} (p_i, \hat p_i) + \lambda \frac{1}{N_{reg}} \sum_i \hat p_i L_{reg}(t_i, \hat t_i)\]

      Trong đó, \(L_{cls}\) là hàm binary cross-entropy, còn \(L_{reg}\) là hàm mất mát hồi quy \(SmoothL1\); \(\hat p_i\) là phân phối xác suất dự đoán hộp đề xuất có đối tượng hay không, \(p_i\) là nhãn thật sự; \(\hat t_i\) là tọa độ dự đoán đã được tham số hóa; \(t_i\) là tọa độ thật đã được tham số hóa, \(t=\{t_x, t_y, t_w, t_h\}\) và \(\hat t=\{\hat t_x, \hat t_y, \hat t_w, \hat t_h\}\) được định nghĩa như sau:

      \(t_x = (x - x_a) / w_a; \hat t_x = (\hat x - x_a) / w_a\) \(t_y = (y - y_a) / h_a; \hat t_y = (\hat y - y_a) / h_a\) \(t_w = \log (w / w_a); \hat t_w = \log (\hat w / w_a)\) \(t_h = \log (h / h_a); \hat t_h = \log (\hat h / h_a)\)

      Trong đó, \(x\), \(\hat x\), \(x_a\) lần lượt là hoành độ tâm thật sự của hộp bao, hoành độ tâm dự đoán của hộp bao và hoành độ tâm anchor box. \(y\), \(\hat y\), \(y_a\) là tung độ tâm. Như thế ta có thể thấy, ở đây RPN không cố gắng để dự đoán các vị trí giống như hộp mỏ neo (vì nếu thế thì sử dụng hộp mỏ neo luôn cần gì học nữa), mà nó sẽ cố gắng dự đoán các vùng đề xuất lân cận các anchor box, mà tại đó có nhiều hộp bao ground-truth.

      Thực tế, RPN sinh ra rất nhiều hộp đề xuất, trong khi chúng ta chỉ cần \(N=2000\) hộp đề xuất. Có nhiều hộp đề xuất ban đầu bị chồng lấp lên nhau, lúc này tác giả sử dụng thuật toán non maximum suppression (NMS) với ngưỡng \(IoU=0.7\) để loại đi các hộp đề xuất chồng lấp, chỉ giữ lại \(2000\) hộp đề xuất để đưa vào Fast R-CNN huấn luyện. Tuy nhiên, khi huấn luyện thì \(N=2000\), trong khi đó lúc đánh giá (test) thì \(N\) là một con số khác (nhỏ hơn 2000).

      Cơ chế chia sẻ trọng số giữa RPN và Fast R-CNN (Sharing Convolutional Features)

      Việc huấn luyện RPN và Fast R-CNN được thực hiện độc lập chứ không end-to-end. Lý do của việc này rất dễ hiểu: rất khó để huấn luyện hai thứ này cùng một lúc. Fast R-CNN cần có một cơ chế sinh mẫu cố định (sinh ra các hộp đề xuất) để học, và bản thân Fast R-CNN cũng có một hàm tối ưu hóa tương tự như RPN (tổng của hàm mất mát phân lớp đối tượng và hàm mất mát hồi quy, nhưng hàm mất mát ở Fast R-CNN dùng cho đa lớp). Do đó không biế rằng nếu cơ chế sinh mẫu liên tục thay đổi (liên tục cập nhật trọng số lại ở RPN) thì mạng hợp nhất này có hội tụ được hay không. Do đó, tác giả đã đề xuất một cơ chế huấn luyện chia sẻ trọng số gồm 4 bước sau đây:

      • Bước 1: Huấn luyện RPN trước
      • Bước 2: Đóng băng trọng số ở RPN, sử dụng mạng RPN vừa học được sinh ra các vùng đề xuất cho mạng Fast R-CNN.
      • Bước 3: Dùng trọng số vừa học được ở mạng Fast R-CNN làm trọng số khởi tạo của mạng RPN ở các lớp tích chập (RPN và Fast R-CNN chia sẻ trọng số ở một số lớp tích chập), và chỉ fine-tune các lớp tích chập của riêng FPN và 2 lớp FC.
      • Bước 4: Đóng băng trọng số ở mạng RPN vừa học để sinh các mẫu cho Fast R-CNN, và chỉ fine-tune Fast R-CNN ở 2 lớp FC.

      Kết quả so với Fast R-CNN

      Hình 5. Kết quả so sánh giữa việc sử dụng RPN và thuật toán Selective Search [3].

      Có thể thấy, việc sử dụng thuật toán Selective Search cho kết quả thấp hơn khi sử dụng RPN. Hơn nữa, tốc độ xử lý của Fast R-CNN sử dụng RPN (Faster R-CNN) cũng nhanh hơn sử dụng thuật toán Selective Search. Vừa tốt hơn vừa nhanh hơn, Faster R-CNN đã trở thành một “hệ tư tưởng”.

      Hướng dẫn huấn luyện thử Faster R-CNN

      Faster R-CNN khá khó để có thể code from scratch. Do đó, trong nội dung bài viết này, nhóm sinh viên hướng dẫn bạn đọc cách huấn luyện thử một mô hình Faster R-CNN thông qua toolbox MMDetection [4].

      Lưu ý: source code được thực nghiệm trên Google Colab.

      Trong bài này, nhóm sinh viên sử dụng bộ dữ liệu UIT-VinaDeveS22 được cung cấp ở đây: https://github.com/nguyenvd-uit/uit-together-dataset/blob/main/UIT-VinaDeveS22.md

      UIT-VinaDeveS22 là bộ dữ liệu phát hiện phương tiện giao thông từ camera CCTV, các phương tiện trong bộ dữ liệu bao gồm: bicycle, motorcycle, car, van, truck, bus, fire truck.

      Hình 6. Hình ảnh bộ dữ liệu UIT-VinaDeveS22

      1. Cài đặt thư viện

      Đầu tiên, chúng ta cần clone toolbox MMDetection từ Github về, sau đó cài đặt các thư viện cần thiết:

      • Bước 1.1: git clone thư mục code 
        !git clone https://github.com/open-mmlab/mmdetection
+
      • Bước 1.2: cài đặt thư viện 
        # Cài đặt thư viện
+%cd mmdetection
+!pip install -r requirements.txt
+!pip install -v -e .
+!pip install mmcv-full==1.3.8 -f https://download.openmmlab.com/mmcv/dist/cu101/torch1.7.0/index.html
+!pip install torch==1.7.1 torchvision==0.8.2 torchaudio==0.7.2
+

      2. Import thư viện

      • Bước 2.1: ta import các thư viện liên quan cần dùng, ở đây chúng ta cần import mmdet, mmcv.
      # Dùng để build config
+import mmdet
+from mmdet.apis import set_random_seed
+from mmcv import Config
+
+# Dùng để xây dựng dataset
+from mmdet.datasets import build_dataset
+from mmdet.models import build_detector
+from mmdet.apis import train_detector
+
+# Dùng để dự đoán
+from mmdet.apis import init_detector, inference_detector, show_result_pyplot
+import mmcv
+

      3. Chuẩn bị dữ liệu

      Tải dữ liệu tại đây: https://drive.google.com/file/d/1NhsIWyPdqF2KDqPWU926eZwCLk0gtjnv/view?usp=sharing

      Ta có thể tải bằng lệnh sau:

      !gdown --id 1NhsIWyPdqF2KDqPWU926eZwCLk0gtjnv
+

      Sau khi tải, chúng ta giải nén dữ liệu bằng lệnh unzip

      !unzip UIT-VinaDeveS22.zip
+

      Bộ dữ liệu được tổ chức theo cấu trúc sau:

      UIT-VinaDeveS22
+|__ images
+|____ *.jpg
+|__ outputtrain.json
+|__ outputvalid.json
+|__ outputtest.json
+

      Thư mục images chứa toàn bộ ảnh của bộ dữ liệu. 3 file ouputtrain.json, outputvalid.json và outputtest.json là 3 file annotation đã được chuẩn bị theo định dạng MS-COCO ứng với 3 tập: train, valid, test.

      4. Chuẩn bị config

      Bước này khá quan trọng. Hiện tại MMDetection đã hỗ trợ cho chúng ta rất nhiều config của nhiều phương pháp SOTA cho phát hiện đối tượng hiện tại, lên tới vài chục phương pháp. Tuy nhiên, chúng ta chỉ sử dụng config dành cho Faster R-CNN.

      • Bước 4.1: Config trong MMDetection được thiết kế theo cơ chế kế thừa, tức là từ config chuẩn bị sẵn, chúng ta sẽ tinh chỉnh cho phù hợp với bộ dữ liệu của chúng ta. Đầu tiên ta cần xác định config cha mà chúng ta sẽ kế thừa
      cfg = Config.fromfile('configs/faster_rcnn/faster_rcnn_r101_fpn_1x_coco.py')
+

      faster_rcnn_r101_fpn_1x_coco.py là file config của phương pháp Faster R-CNN, sử dụng kiến trúc CNN ResNet-101 để trích xuất đặc trưng ảnh (là các lớp conv chung của mạng RPN và Fast R-CNN). Trong đó có sử dụng FPN (một cơ chế multi-scale feature map, tức là thay vì qua mạng CNN chỉ có 1 đầu ra thì nó sẽ có nhiều đầu ra với các resolution khác nhau).

      • Bước 4.2: Ta cần định nghĩa lại dữ liệu. MMDetection hỗ trợ các bộ dữ liệu sẵn có như COCO, sử dụng bộ dữ liệu khác ta cần định nghĩa lại các lớp. Tuy nhiên do cấu trúc bộ dữ liệu cũng giống như COCO, ta chỉ kế thừa nó về chỉnh lại các lớp sao cho phù hợp:
      from mmdet.datasets.builder import DATASETS
+from mmdet.datasets import CocoDataset
+
+@DATASETS.register_module()
+class VinaDeveS22(CocoDataset):
+    CLASSES = ('bicycle', 'motorcycle', 'car', 'van', 'truck', 'bus', 'fire truck')
+
      • Bước 4.3: ta đặt đường dẫn cho tập dữ liệu, bao gồm đường dẫn ảnh, annotation cho tập train, test, valid:
      # Đường dẫn dữ liệu
+import os
+data_root_dir = '/content/drive/MyDrive/BDL_UIT/UIT-VinaDeveS22/'
+
+# Chuẩn bị config
+
+cfg = Config.fromfile('configs/faster_rcnn/faster_rcnn_r101_fpn_1x_coco.py')
+
+# Modify dataset type and path
+cfg.data_root = data_root_dir
+
+cfg.data.test.type = 'VinaDeveS22'
+cfg.data.test.ann_file = os.path.join(data_root_dir, 'outputtest.json')
+cfg.data.test.img_prefix = os.path.join(data_root_dir, 'images')
+
+cfg.data.train.type = 'VinaDeveS22'
+cfg.data.train.ann_file = os.path.join(data_root_dir, 'outputtrain.json')
+cfg.data.train.img_prefix = os.path.join(data_root_dir, 'images')
+
+cfg.data.val.type = 'VinaDeveS22'
+cfg.data.val.ann_file = os.path.join(data_root_dir, 'outputvalid.json')
+cfg.data.val.img_prefix = os.path.join(data_root_dir, 'images')
+
      • Bước 4.4: Một số cấu hình khác như số epoch để save checkpoint 1 lần, learning rate, đường dẫn lưu checkpoint, số lớp cần classify của mô hình, …
      # Một số cấu hình khác
+
+cfg.optimizer.lr = 0.02 / 8
+cfg.lr_config.warmup = None
+cfg.log_config.interval = 500
+
+# We can set the evaluation interval to reduce the evaluation times
+cfg.evaluation.interval = 1
+# We can set the checkpoint saving interval to reduce the storage cost
+cfg.checkpoint_config.interval = 3
+
+# Set seed thus the results are more reproducible
+cfg.seed = 0
+set_random_seed(0, deterministic=False)
+cfg.gpu_ids = range(1)
+
+# Số class
+cfg.model.roi_head.bbox_head.num_classes = 7
+
+# Đường dẫn lưu checkpoints
+cfg.work_dir = './checkpoints'
+

      5. Xây dựng model và huấn luyện

      Ta tiến hành xây dựng mô hình dựa trên config đã chuẩn bị:

      # Build dataset
+datasets = [build_dataset(cfg.data.train)]
+
+# Build the detector
+model = build_detector(cfg.model, train_cfg=cfg.get('train_cfg'), test_cfg=cfg.get('test_cfg'))
+# Add an attribute for visualization convenience
+model.CLASSES = ('bicycle', 'motorcycle', 'car', 'van', 'truck', 'bus', 'fire truck')
+

      Tiến hành huấn luyện:

      train_detector(model, datasets, cfg, distributed=False, validate=True)
+

      Log khi huấn luyện:

      FALFormer: Feature-aware Landmarks self-attention for Whole-slide Image Classification

      Doanh C. Bui, Trinh T. L. Vuong, Jin Tae Kwak

      Abstract: Slide-level classification for whole-slide images (WSIs) has been widely recognized as a crucial problem in digital and computational pathology. Current approaches commonly consider WSIs as a bag of cropped patches and process them via multiple instance learning due to the large number of patches, which cannot fully explore the relationship among patches; in other words, the global information cannot be fully incorporated into decision making. Herein, we propose an efficient and effective slide-level classification model, named as FALFormer, that can process a WSI as a whole so as to fully exploit the relationship among the entire patches and to improve the classification performance. FALFormer is built based upon Transformers and self-attention mechanism. To lessen the computational burden of the original self-attention mechanism and to process the entire patches together in a WSI, FALFormer employs Nystrom self-attention which approximates the computation by using a smaller number of tokens or landmarks. For effective learning, FALFormer introduces feature-aware landmarks to enhance the representation power of the landmarks and the quality of the approximation. We systematically evaluate the performance of FALFormer using two public datasets, including CAMELYON16 and TCGA-BRCA. The experimental results demonstrate that FALFormer achieves superior performance on both datasets, outperforming the state-of-the-art methods for the slide-level classification. This suggests that FALFormer can facilitate an accurate and precise analysis of WSIs, potentially leading to improved diagnosis and prognosis on WSIs.

      Our study “Improving Human-object Interaction with Auxiliary Semantic Information and Enhanced Instance Representation” has been accepted to be published by “Pattern Recognition Letters” (SCI, Q1, IF = 5.1). I want to give special thanks to Thinh V. Le and Huyen Nguyen for their efforts in this work. This study is also the result of undergraduate thesis of Thinh & Huyen. This study is also on collaboration with UIT-Together Research Group. In this work, we propose three key modules: Enhanced Interaction Pointers (EIP), Semantic-guided (SG) and Multi-level cross-attention (MCA) based on the HOTR model to improve itself for human-object interaction (HOI) problem.

      Authorship contribution statement:

      • Khang Nguyen: Project administration, Supervision, Idea confirmation.
      • Thinh V. Le: Implementation (Idea implementation, feature extraction, training & evaluation on two benchmarks: V-COCO and HICO-DET), Writing – review & editing
      • Huyen Nguyen: Writing (specially focus on linguistic aspects) – review & editing
      • Doanh C. Bui: Conceptualization (EIP, SG, MCA), Implementation (only support Thinh V. Le), Writing – review & editing

      We will publish our source code and checkpoints for this study soon!

      P/s: I really appreciate the efforts of two undergraduate students: Thinh V. Le and Huyen Nguyen, who were working with me when we were all undergraduate students, to complete this study, specially Thinh. Thinh is a hard-working student. His self-study ability, knowledge, and coding are very good. Most of works of implementation in this study are done by him. I hope that in the future, I will have chance to continue to do research with Thinh. And I wish he will continue to develop himself, leverage all chances coming to him, to become an excellent student in the future! Huyen Nguyen also showed her effort and performed co-working ability pretty well, I also believe that she will achieve further achievements in the future.

      P/s 2: We all know that papers are just the results of researching period, and they are not that all, they are just some milestones. We should continue to try our best in the academic career, to bring not only theorical but also practical research to the community. There is a long road to go for achieving this.

      This image can also have a caption. It's like magic.

      You can also put regular text between your rows of images. Say you wanted to write a little bit about your project before you posted the rest of the images. You describe how you toiled, sweated, bled for your project, and then… you reveal its glory in the next row of images.

      You can also have artistically styled 2/3 + 1/3 images, like these.

      The code is simple. Just wrap your images with <div class="col-sm"> and place them inside <div class="row"> (read more about the Bootstrap Grid system). To make images responsive, add img-fluid class to each; for rounded corners and shadows use rounded and z-depth-1 classes. Here’s the code for the last row of images above:

      You can also put regular text between your rows of images. Say you wanted to write a little bit about your project before you posted the rest of the images. You describe how you toiled, sweated, bled for your project, and then… you reveal its glory in the next row of images.

      You can also have artistically styled 2/3 + 1/3 images, like these.

      The code is simple. Just wrap your images with <div class="col-sm"> and place them inside <div class="row"> (read more about the Bootstrap Grid system). To make images responsive, add img-fluid class to each; for rounded corners and shadows use rounded and z-depth-1 classes. Here’s the code for the last row of images above:

      <div class="row justify-content-sm-center">

      Every project has a beautiful feature showcase page. It’s easy to include images in a flexible 3-column grid format. Make your photos 1/3, 2/3, or full width.

      To give your project a background in the portfolio page, just add the img tag to the front matter like so:
