Sebastian Seung Dept. Abstract: Nonnegative Matrix Factorization (NMF) is valuable in many applications of blind source separation, signal processing and machine learning. We derive algorithms for finding a nonnegative n-dimensional tensor factorization (n-NTF) which includes the non-negative matrix factorization (NMF) as a particular case when n = 2. We use a multiscale approach to reduce the time to produce the nonnegative matrix factorization (NMF) of a matrix A, that is, A ≈ WH. The approximate Nonnegative Matrix Factorization (NMF) of nonnegative ma-trices is a data analysis technique only recently introduced [6, 10]. 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. 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.

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. The development and use of low-rank approximate nonnegative matrix factorization (NMF) algorithms for feature extraction and identification in the fields of text mining and spectral data analysis are presented. However, the extraordinary effectiveness of NMF in analyzing real-life nonnegative data has sparked a substantial amount of research in many fields. Nonnegative matrix factorization (NMF) is a data analysis technique used in a great variety of applications such as text mining, image processing, hyperspectral data analysis, computational biology, and clustering. 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 … Nonnegative Matrix Factorization: Algorithms and Applications Haesun Park hpark@cc.gatech.edu School of Computational Science and Engineering Georgia Institute of Technology Atlanta, GA, USA SIAM International Conference on Data Mining, April, 2011 This work was supported in part by the National Science Foundation.
