PiPNN: Ultra-Scalable Graph-Based Nearest Neighbor Indexing

cs.DB · 2026-02-17 · conditional · novelty 6.0

PiPNN builds high-quality approximate-nearest-neighbor search graphs up to 12.9x faster than HNSW and 11.6x faster than Vamana by replacing search-based construction with overlapping partitions, dense GEMM distance computations, and an LSH-based online pruning rule.
