Semiring rank matrix factorization
WebAbstract Using elementary linear algebra, we develop a technique that leads to solutions of two widely known problems on nonnegative matrices. First, we give a short proof of the result by Vavasis stating that the nonnegative rank of a matrix is NP-hard to compute.

Webis based on the concept of semiring matrix factorisation. In this framework, we employ the max-product semiring rather than the plus-product semiring common in traditional linear … Webrank approximate matrix factorization comes from the previously developed regression algorithms. Max-times algebra concerns the max-times semiring, which is the algebra of the non-negative real numbers along with the binary operations max and times. Although max-plus and max-times are isomorphic as algebraic structure, via the map h: R max+ 7!R
