RoarGraph: A Projected Bipartite Graph for Efficient Cross-Modal Approximate Nearest Neighbor Search

Summary: Shows cross-modal (OOD) queries spatially deviate from base embeddings and their k-NNs are mutually distant, breaking assumptions of existing ANNS graphs. Proposes RoarGraph, a query-distribution–guided projected bipartite graph index that yields up to 3.56× faster search at 90% recall on cross-modal datasets. (summarized by gpt-5-mini on Feb 09 2026)
