CubeGraph: Efficient Retrieval-Augmented Generation for Spatial and Temporal Data
Mingyu Yang, Wentao Li, Wei Wang
Hybrid queries combining high-dimensional vector similarity search with spatio-temporal filters are increasingly critical for modern retrieval-augmented generation (RAG) systems. E…
Reverse Neighbor Sliding and Order Selection for Efficient Multi-Proximity Graph Merging
Liuchang Jing, Mingyu Yang, Lei Li +2
Approximate k Nearest Neighbor (AKNN) search in high-dimensional space is a foundational problem in vector databases with widespread applications. Among the numerous AKNN indexes,…
E2E: Efficient Filtered AKNN Search via Adaptive Termination
Wenxuan Xia, Mingyu Yang, Wentao Li +1
Approximate k-Nearest Neighbor (AKNN) search is widely used in vector databases. When vectors carry additional attributes (e.g., labels or numerical values), filtered AKNN search r…
Elastic Index Selection for Label-Hybrid AKNN Search
Mingyu Yang, Wenxuan Xia, Wentao Li +2
Real-world vector embeddings are usually associated with extra labels, such as attributes and keywords. Many applications require the nearest neighbor search that contains specific…
ESG: Elastic Graphs for Range-Filtering Approximate k-Nearest Neighbor Search
Mingyu Yang, Wentao Li, Zhitao Shen +2
Range-filtering approximate -nearest neighbor (RFAKNN) search takes as input a vector and a numeric value, returning points from a database of high-dimensional points. T…
Quantization Meets Projection: A Happy Marriage for Approximate k-Nearest Neighbor Search
Mingyu Yang, Liuchang Jing, Wentao Li +1
Approximate -nearest neighbor (AKNN) search is a fundamental problem with wide applications. To reduce memory and accelerate search, vector quantization is widely adopted. Howev…
Effective and General Distance Computation for Approximate Nearest Neighbor Search
Mingyu Yang, Wentao Li, Jiabao Jin +5
Approximate K Nearest Neighbor (AKNN) search in high-dimensional spaces is a critical yet challenging problem. In AKNN search, distance computation is the core task that dominates…
