LES3: Learning-based Exact Set Similarity Search

Summary: LES3 introduces a learning-based exact set similarity search that partitions sets and uses a TGM bitmap index to prune candidates. Analytical partitioning under distributional assumptions informs L2P and PTR, enabling pruning and faster exact search than baselines. (summarized by gpt-5-nano on Feb 09 2026)
