Update rules for the Non-negative Matrix Factorization. This follows a method titled 'Alternating Least Squares' described in the paper 'Positive Matrix Factorization: A Non-negative Factor Model with Optimal Utilization of Error Estimates of Data Values' by P. Paatero and U. Tapper. It uses least squares projection formula to reduce the error value of by alternately calculating W and H respectively while holding the other matrix constant.
