Abstract

The aim of nmf is to decompose matrix A into a lower-rank matrix approximation such that X ≈ WH, where A, W and H are made up of non-negative, real numbers. Missing values are permitted. If X is an n x m matrix, the dimensions of W and H will be n x k and k x m, respectively, whereby k represents the rank of the decomposition. In many cases, a good approximation for A may be achieved with k
