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

Ramakrishnan Kannan, Grey Ballard, Haesun Park

Non-negative matrix factorization (NMF) is the problem of determining two non-negative low rank factors $W$ and $H$ , for the given input matrix $A$ , such that $A \approx W H$ . NMF…
