arXiv:2607.02338v1 Announce Type: cross Abstract: Hierarchical Navigable Small World (HNSW) graphs serve as the industry standard due to their logarithmic complexity and strong empirical performance. However, HNSW relies on greedy graph traversal, a heuristic that provides no theoretical guarantees of correctness. In this paper, we propose a novel "Certify-then-Rectify" framework that bridges the gap between the speed of heuristic search and the rigor of exact retrieval. Rather than discarding HNSW, our approach first employs a distribution-free statistical certifier to dynamically evaluate th
The continuous drive for more efficient and reliable AI systems, especially in areas like information retrieval and recommenders, pushes for improvements in fundamental graph algorithms like HNSW.
This development addresses a critical limitation in widely used AI components by introducing theoretical guarantees for accuracy, which could accelerate broader adoption in sensitive applications and improve robustness.
HNSW, a de facto industry standard, can now offer certified correctness alongside its speed, potentially making it suitable for a wider range of applications where guarantees are crucial.
