Web20 mei 2012 · Traditionally, several LSH functions are concatenated to form a "static" compound hash function for building a hash table. In this paper, we propose to use a base of m single LSH functions to construct " dynamic " compound hash functions, and define a new LSH scheme called Collision Counting LSH (C2LSH).
