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 $ \sqrt{\sum_i \sum_j(V-WH)^2} $ by alternately calculating W and H respectively while holding the other matrix constant\&.
