We present a generalization of the nonnegative matrix factorization (NMF), where a multilayer generative network with nonnegative weights is used to approximate the observed nonnegative data. The multilayer generative network with nonnegativity constraints, is learned by a multiplicative uppropagation algorithm, where the weights in each layer are updated in a multiplicative fashion while the mismatch ratio is propagated from the bottom to the top layer. The monotonic convergence of the… CONTINUE READING
