Nonnegative matrix factorization (NMF) is a multivariate method that approximates a given nonnegative matrix by the product of two low-rank nonnegative matrices, and has been widely used in signal processing, text classification, network analysis, and recommendation systems. In this report, assuming that a given nonnegative matrix is divided into a large number of blocks and each block is assigned to a single agent, we propose an algorithm for multiple agents to perform NMF in a decentralized and cooperative manner. The proposed algorithm, which is a combination of various multiplicative updates and a certain consensus algorithm, gives the same results as performing multiplicative updates with a single agent. |
