Exact multiplicative updates for convolutional -NMF in 2D
Pedro J. Villasana T., Stanislaw Gorlow
In this paper, we extend the -CNMF to two dimensions and derive exact multiplicative updates for its factors. The new updates generalize and correct the nonnegative matrix facto…

Multiplicative Updates for Convolutional NMF Under -Divergence
Pedro J. Villasana T., Stanislaw Gorlow, Arvind T. Hariraman
In this letter, we generalize the convolutional NMF by taking the -divergence as the contrast function and present the correct multiplicative updates for its factors in closed f…
