Our interests lies in high-dimensional vector data management (and its applications in large models such as retrieval-augmented generative AI).
Large-scale high-dimensional vector data has become ubiquitous in contemporary times. 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.
