Lsh algorithm
WebSensitive Hashing (LSH) [15], [10]. LSH is a name for a set of hashing algorithms, and we can specifically design different LSH algorithms for different types of data [10]. For real vectors, random-projection-based LSH [5] might be the most simple and popular one. This algorithm uses random projection to partition the feature space. WebLSH , SH , ITQ , KMH and PRH belong to the shallow hashing algorithms, and their performances relate to the quality of the intermediate high dimensional features. To eliminate this effect, TOCEH, TBH [ 10 ], DVB [ 39 ], DH [ 40 ], DeepBit [ 41 ] and DCH [ 11 ] adopt a deep learning framework to learn the end-to-end binary feature, which can …

In computer science, locality-sensitive hashing (LSH) is an algorithmic technique that hashes similar input items into the same "buckets" with high probability. (The number of buckets is much smaller than the universe of possible input items.) Since similar items end up in the same buckets, this … Meer weergeven An LSH family $${\displaystyle {\mathcal {F}}}$$ is defined for • a metric space $${\displaystyle {\mathcal {M}}=(M,d)}$$, • a threshold $${\displaystyle R>0}$$, Meer weergeven One of the main applications of LSH is to provide a method for efficient approximate nearest neighbor search algorithms.
