Subspace Collision: An Efficient and Accurate Framework for High-dimensional Approximate Nearest Neighbor Search

Summary: Subspace Collision (SC) yields theoretical guarantees for high-d ANN via SC-score, a Pareto-distance proxy, and SuCo's clustering-based, lightweight index. Experiments show 1-2 orders of magnitude faster queries with <=1/10 memory, beating guarantee-enabled baselines. (summarized by gpt-5-nano on Feb 09 2026)
