Īnother type of NMF for images is based on the total variation norm. Let matrix V be the product of the matrices W and H, It became more widely known as non-negative matrix factorization after Lee and Seung investigated the properties of the algorithm and published some simple and usefulĪlgorithms for two types of factorizations. In this framework the vectors in the right matrix are continuous curves rather than discrete vectors.Īlso early work on non-negative matrix factorizations was performed by a Finnish group of researchers in the 1990s under the name positive matrix factorization. In chemometrics non-negative matrix factorization has a long history under the name "self modeling curve resolution". NMF finds applications in such fields as astronomy, computer vision, document clustering, missing data imputation, chemometrics, audio signal processing, recommender systems, and bioinformatics. Since the problem is not exactly solvable in general, it is commonly approximated numerically. Also, in applications such as processing of audio spectrograms or muscular activity, non-negativity is inherent to the data being considered. This non-negativity makes the resulting matrices easier to inspect. Non-negative matrix factorization ( NMF or NNMF), 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.
