Boolean Matrix Factorization via Nonnegative Auxiliary Optimization

Duc P. Truong,
Erik Skau,
Derek Desantis
et al.

Abstract: A novel approach to Boolean matrix factorization (BMF) is presented. Instead of solving the BMF problem directly, this approach solves a nonnegative optimization problem with the constraint over an auxiliary matrix whose Boolean structure is identical to the initial Boolean data. Then the solution of the nonnegative auxiliary optimization problem is thresholded to provide a solution for the BMF problem. We provide the proofs for the equivalencies of the two solution spaces under the existence of an exact solut… Show more
