    Experiments with the NNMFPACK library: influence of beta parameter in the NNMF approximation error 
    San Juan Sebastián, Pablo; Vidal Maciá, Antonio Manuel; García Mollá, Víctor Manuel; Martínez Zaldívar, Francisco José; Ranilla, J.; Alonso, P.; Alonso-González, M.; Cortina, R. (CMMSE, 2015-07)
    [EN] NnmfPack is a numerical library designed to compute efficiently the Non-Negative Matrix Factorization (NNMF). It has been conceived for shared memory heterogeneous parallel systems, and it supports, from its conception, ...

    Improving NNMFPACK with heterogeneous and efficient kernels for ß-divergence metrics 
    Díaz-Gracia, N.; Cocaña-Fernández, A.; Alonso-González, M:; Martínez Zaldívar, Francisco José; Cortina, Raquel; García Mollá, Víctor Manuel; Alonso, P.; Ranilla, J.; Vidal Maciá, Antonio Manuel (Springer Verlag (Germany), 2015-05)
    NnmfPack is a library for the nonnegative matrix factorization (NNMF) problem. Nowadays NNMF is an essential tool in many fields spanning machine learning, data analysis, image analysis or audio source separation, among ...

    Parallel approach to NNMF on multicore architecture 
    Alonso, P.; García Mollá, Víctor Manuel; Martínez Zaldívar, Francisco José; Salazar Afanador, Addisson; Vergara Domínguez, Luís; Vidal Maciá, Antonio Manuel (Springer Verlag (Germany), 2014-11)
    We tackle the parallelization of Non-Negative Matrix Factorization (NNMF), using the Alternating Least Squares and Lee and Seung algorithms, motivated by its use in audio source separation. For the first algorithm, a very ...

    Updating/downdating the NonNegative Matrix Factorization 
    San Juan Sebastián, Pablo; Vidal Maciá, Antonio Manuel; García Mollá, Víctor Manuel (Elsevier, 2016-12-08)
    The Non-Negative Matrix Factorization (NNMF) is a recent numerical tool that, given a nonnegative data matrix, tries to obtain its factorization as the approximate product of two nonnegative matrices. Nowadays, this ...
