Dynamically Detect and Fix Hardness for Efficient Approximate Nearest Neighbor Search
Summary: Propose Escape Hardness, a per-query metric to locate defective regions in graph-based ANNS and a two-stage online repair that fixes them on-the-fly without bipartite graphs or costly rebuilds. RFix (entry) and NGFix (vicinity) improve OOD robustness and speed (up to 2.25×).
