MPI-FAUN: An MPI-Based Framework for Alternating-Updating Nonnegative Matrix Factorization.

Non-negative matrix factorization (NMF) is the problem of determining two non-negative low rank factors Wand H, for the given input matrix A, such that A WH. NMF is a useful tool for many applications in different domains such as topic modeling in text mining, background separation in video analysis, and community detection in social networks. Despite its popularity in the data mining community, t...
