RWalks: Random Walks as Attribute Diffusers for Filtered Vector Search

Summary: RWalks: index-agnostic graph-based filtered vector search with random-walk diffusion for both filtered and unfiltered queries. Scales to 100M vectors; beats ACORN: 2x faster filtered search, 76x faster index builds, 13x faster unfiltered search. (summarized by gpt-5-nano on Feb 09 2026)
