Heuristics for exact nonnegative matrix factorization

Gillis, Nicolas; Glineur, François; Tuyttens, Daniel; … - Center for Operations Research and Econometrics (CORE), … - 2015

The exact nonnegative matrix factorization (exact NMF) problem is the following: given an m-by-n nonnegative matrix X … and a factorization rank r, find, if possible, an m-by-r nonnegative matrix W and an r-by-n nonnegative matrix H such that … factorization rank such that an exact NMF exists. In particular, we disprove a conjecture on the nonnegative rank of a Kronecker …
