A Weighted Regularized Matrix Factorization Algorithm is a weighted matrix factorization algorithm that is a regularized matrix factorization algorithm with optimization criterion of [math]\displaystyle{ \Sigma_{u \in U} \Sigma_{i \in I} \ C_{ui}( \langle w_u, h_i \rangle - 1)^2 + \lambda \|{W}\|^2_f + \lambda \|{H}|^2_f }[/math] where [math]\displaystyle{ c_{ui} }[/math] are not model parameters.
