On the Complexity of Low-Rank Matrix Signing and Entrywise Power Matrix Factorization

Nicolas Gillis, Subhayan Saha, Stefano Sicilia +1

Given a nonnegative matrix $X$ , a factorization rank $r$ and {a positive integer $p$ }, entrywise power matrix factorization (EPMF) looks for a low-rank matrix $X_{r}$ such that $X =…

Manifold-based Algorithms for the Hadamard Decomposition

Nicolas Gillis, Subhayan Saha, Stefano Sicilia +1

Given a matrix $X$ , and two ranks $r_{1}$ and $r_{2}$ , the Hadamard decomposition (HD) looks for two low-rank matrices, $X_{1}$ of rank $r_{1}$ and $X_{2}$ of rank $r_{2}$ , both of the same si…
