locality-sensitive hashing 简单理解 LSH是为了将向量hash到多个桶里以索引以缩小计算向量相似度时的候选。
局部敏感哈希压缩(LSH):最早在1998年,Piotr Indyk在Stanford读PHD时与导师Rajeev Motwani提出一种hash方法:Locality Sensitive Hashing。Approximate Nearest Neighbors: Towards Removing the Curse of Dimensionality。1999年Piotr Indyk的同门师弟Aristides Gionis对之前的LSH雏形算法进行完善发表了Similarity Search in High Di...
The hash function is "locality-sensitive", as the probability of two strings hashing to the same value varies in direct proportion with their pairwsie similarity [25]. Given two similar strings s x and s y which contain at the most p different nucleotides, the probability of their hash ...

一、LSH介绍LSH(Localitysensitivehashing)是局部敏感性hashing,它与传统的hash是不同的。传统hash的目的是希望得到O(1)的查找性能,将原始数据映射到相应的桶内。LSH的基本思想是将空间中原始数据相邻的2个数据点通过映射或者投影变换后,这两个数据点在新的空间中的相邻概率很大,不相邻的点映射到同一个桶的概率小。
