For instance, various forms of unstructured data, such as images, videos, texts, and speeches, are typically transformed into vectors using deep learning techniques. These vectors are subsequently employed in downstream analytical tasks. Nearest neighbor (NN) search in high-dimensional vector space constitutes a fundamental problem with a wide array of applications in information retrieval, recommendations, and retrieval-based large language models.

He received his PhD degree from the Hong Kong University of Science and Technology, Hong Kong, in 2015, and his BEng degree from South China University of Technology, China, in 2010.<br>Cheng Long has research interests broadly in data management and data mining. Specifically, he works in high-dimensional vector data management (and its applications in large models such as retrieval-augmented generative AI), spatial data management with machine learning-based techniques, spatial data mining in the urban domain (e.g., traffic and mobility analysis), and graph data mining (including dense subgraph mining and graphlet mining).</p></div></div><br><br><h2 id=research-students>Research Students</h2><div style=display:flex;align-items:flex-start><div style=flex-shrink:0;text-align:center><div style=width:165px;height:220px;overflow:hidden;margin-right:20px;border-radius:15px><img src=https://www3.ntu.edu.sg/scse/dmal/dante/images/Gao%20Jianyang_photo.jpg alt="Profile Image" style=width:100%;height:100%;object-fit:cover;border-radius:15px></div><div style=width:165px;display:flex;justify-content:center;margin-top:10px><a href="mailto: jianyang.gao@ntu.edu.sg" style=margin-right:10px;color:#003056><i class="fas fa-envelope" style=font-size:24px></i>
