Locality-Sensitive Hashing Techniques for Nearest Neighbor Search
Keon Myung Lee · International Journal of Fuzzy Logic and Intelligent Systems · 2012
When the volume of data grows big, some simple tasks could become a significant concern. Nearest neighbor search is such a task which finds from a data set the k nearest data points to queries. Locality-sensitive hashing techniques have been developed for approximate but fast nearest neighbor search. This paper introduces the notion of locality-sensitive hashing and surveys the locality-sensitive hashing techniques. It categories them based on several criteria, presents their characteristics, and compares their performance.
