WebMay 9, 2016 · Parameter-free Locality Sensitive Hashing for Spherical Range Reporting. We present a data structure for *spherical range reporting* on a point set , i.e., reporting all points in that lie within radius of a given query point . Our solution builds upon the Locality-Sensitive Hashing (LSH) framework of Indyk and Motwani, which represents the ... WebMay 3, 2016 · One simple way to generate a hash function for LSH is as follows: For a given min-hash signature i for each band b, compute the sum of rows in the band, call it S_ib. Create a bucket for S_ib. For the complete set, the bucket will be appended with entries where the sum matches S_ib, otherwise a new bucket is generated.
