Perturbation of matrices and non-negative rank with a view toward statistical models
Cristiano Bocci, Enrico Carlini, Fabio Rapallo
In this paper we study how perturbing a matrix changes its non-negative rank. We prove that the non-negative rank is upper-semicontinuos and we describe some special families of pe…
