... The following properties, which we give without proof, are essential background in the use of vectors and matrices in digital image processing. In each case, we assume a real matrix of order m×m although, as stated earlier, these results are equally applicable to complex numbers. 1. If {1, 2,…, q ...

Non-negative matrix factorization

NMF redirects here. For the bridge convention, see new minor forcing.Non-negative matrix factorization (NMF), also non-negative matrix approximation is a group of algorithms in multivariate analysis and linear algebra where a matrix V is factorized into (usually) two matrices W and H, with the property that all three matrices have no negative elements. This non-negativity makes the resulting matrices easier to inspect. Also, in applications such as processing of audio spectrograms non-negativity is inherent to the data being considered. Since the problem is not exactly solvable in general, it is commonly approximated numerically.NMF finds applications in such fields as computer vision, document clustering, chemometrics, audio signal processing and recommender systems.
