In [[data compression]], '''Vectorvector [[quantization]]''' is a technique used in (usually lossy) [[data compressionlossy]].) in which the The basic idea is to code a multidimensional [[vector space]] space into a sub-space[[subspace]] withof lower dimension. The lower-space vector requires less storage space and the data is thus compressed. The transformation into the sub-space is usually achieved through [[projection]], or by using a code-book.
