Spherical locality sensitive hashing lsh
WebRecently, it was shown that angular locality-sensitive hashing (LSH) can be used to significantly speed up lattice sieving, leading to a heuristic time complexity for solving the shortest vector problem (SVP) of 2 0.337 n + o ( n) (and space complexity 2 0.208 n + o ( n). We study the possibility of applying other LSH methods to sieving, and ... WebFeb 25, 2024 · Locality sensitive hashing can be used in many places. The music identification engine is an obvious one, where we would basically hash songs in the database into buckets. Then, we would perform the same hashing on the user input, see which bucket it lands on, and only query those candidates within the same bucket.
