Off-diagonal Symmetric Nonnegative Matrix Factorization

10 Mar 2020 Moutier François Vandaele Arnaud Gillis Nicolas

Symmetric nonnegative matrix factorization (symNMF) is a variant of nonnegative matrix factorization (NMF) that allows to handle symmetric input matrices and has been shown to be particularly well suited for clustering tasks. In this paper, we present a new model, dubbed off-diagonal symNMF (ODsymNMF), that does not take into account the diagonal entries of the input matrix in the objective function... (read more)
