PM-LSH: A Fast and Accurate LSH Framework for High-Dimensional Approximate NN Search

Summary: PM-LSH uses a PM-tree index with a tunable confidence interval to enable fast, accurate c-ANN in high dimensions. An efficient algorithm atop the PM-tree prunes candidates and improves speed and accuracy over prior LSH. (summarized by gpt-5-nano on Feb 09 2026)
