'''Non-negative matrix factorization''' (NMF) is a group of [[algorithm]]s in [[multivariate analysis]] and [[linear algebra]] where a [[matrix (mathematics)|matrix]], <math>\mathbf{X}</math>, is factorized into (usually) two matrices, <math>\mathbf{W}</math> and <math>\mathbf{H}</math>

: <math>\operatorname{nmf}(\mathbf{X}) \rightarrow \mathbf{WH} </math>
