In this report the derivation and prove of convergence of a weighted non-negative factorization of the form FH*G is discussed. The derivation and proof is based on Lee and Seung's original derivation of Non-negative Matrix Factorization . This form is particularly suited to factor matrices exhibiting a band-diagonal structure with horizontal and vertical discontinuities.
