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

Summary: Shows cross-modal OOD queries violate conventional ANNS assumptions: they deviate spatially and have mutually distant neighbors. RoarGraph exploits query distributions via a projected bipartite graph, delivering up to 3.56× faster search at 90% recall. (summarized by gpt-5.6-luna on Jul 24 2026)
