Hashing numericals

WebA hash function is a mathematical function that converts a numerical input value into another compressed numerical value. The input to the hash function is of arbitrary length but output is always of fixed length. Values returned by a hash function are called message digest or simply hash values. The following picture illustrated hash function −. WebThe original formulation of the hashing trick by Weinberger et al. used two separate hash functions \(h\) and \ ... However the raw data, a sequence of symbols cannot be fed directly to the algorithms themselves as most of them expect numerical feature vectors with a fixed size rather than the raw text documents with variable length.
