TY - JOUR ID - 899282 AU - Novák, David - Kyselák, Martin - Zezula, Pavel PY - 2010 TI - On Locality-sensitive Indexing in Generic Metric Spaces PB - ACM Press CY - New York SN - 9781450304207 KW - locality-sensitive hashing KW - metric space KW - similarity search KW - approximation KW - scalability N2 - The concept of Locality-sensitive Hashing (LSH) has been successfully used for searching in high-dimensional data and a number of locality-preserving hash functions have been introduced. In order to extend the applicability of the LSH approach to a general metric space, we focus on a recently presented Metric Index (M-Index), we redefine its hashing and searching process in the terms of LSH, and perform extensive measurements on two datasets to verify that the M-Index fulfills the conditions of the LSH concept. We widely discuss "optimal" properties of LSH functions and the efficiency of a given LSH function with respect to kNN queries. The results also indicate that the M-Index hashing and searching is more efficient than the tested standard LSH approach for Euclidean distance. ER -
