soft_cofact: smooth nonnegative matrix factorisation and co-factorisation
By N. Seichepine

soft_cofact is a set of Matlab scripts, written by N. Seichepine, which compute both:

  • l2-smooth and piecewise constant (l1-smooth, TV-like) nonnegative matrix factorisation (NMF);

  • and soft nonnegative matrix co-factorisation with IS or KL divergence and l1 or l2 coupling, useful for multiview and multimodal settings.
