Algorithms and applications for approximate nonnegative matrix factorization . The linear algebra community has shown interest in nonnegative matrices and nonnegative matrix factorization (known as nonnegative rank factorization) since more than thirty years ago [3]. Approximate matrix factorization techniques with both nonnegativity and orthogonality constraints, referred to as orthogonal nonnegative matrix factorization (ONMF), have been recently introduced and shown to work remarkably well for clustering tasks such as document classification. These nonnegative factors can be interpreted in the same way as the data, e.g., as images (described by pixel intensities) or texts (represented by vectors of word counts), and lead to an additive and sparse representation. of Brain and Cog. pp. Cichocki A, Zdunek R, Amari S.

The factorization uses an iterative algorithm starting with random initial values for W and H.Because the root mean square residual D might have local minima, repeated factorizations might yield different W and H.Sometimes the algorithm converges to a solution of lower rank than k, which can indicate that the result is not optimal.

Abstract—Nonnegative matrix factorization (NMF) is a widely-used method for multivariate analysis of nonnegative data, the goal of which is decompose a data matrix into a basis matrix and an encoding variable matrix with all of these matrices allowed to have only nonnegative elements. The nonnegative rank becomes thus equal to the rank, so if we fix k =rk +(A) we obtain a trivial solution (W =I and H … In applications, usually A is a matrix of real measurements, distances or intensities, so it is often affected by random noise, that makes it a full-rank matrix. Sci. NMF aims to extract However, the extraordinary effectiveness of NMF in analyzing real-life nonnegative data has sparked a substantial amount of research in many fields.
