Hashing. Hashing in simple words is the transformation of a string of characters into a usually shorter fixed-length value (also called “key”) that represents the original string.

Web27 mei 2011 · If the strings are equidistant from a reference string then chances are that they are similar to each other. And there you go you have a locality senitive hash implementation for strings. You can create different hash buckets for a range of distances. EDIT: You can try other variations of string distance. A simpler algorithm would just return ... 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.
