Nearest-Neighbor Searching Under Uncertainty

Summary: Handles nearest-neighbor queries under probabilistic location uncertainty (points/queries as PDFs), defining the expected nearest neighbor (ENN) objective. Gives first nontrivial exact and ε-approx ENN algorithms with near-linear indexes, polylog/sublinear queries and provable guarantees. (summarized by gpt-5-mini on Feb 09 2026)
