SK-LSH: An Efficient Index Structure for Approximate Nearest Neighbor Search

Summary: SK-LSH imposes a linear order on compound LSH keys using a novel distance measure, co-locating nearby candidates in index pages. It cuts random I/O and verification cost while improving ANN accuracy versus LSB, C2LSH, and CK-Means. (summarized by gpt-5.6-luna on Jul 24 2026)
