Nonnegative Matrix Factorization (NMF) is an operation that decomposes a given nonnegative matrix into two nonnegative factor matrices. NMF is formulated as a constrained optimization problem in which an error has to be minimized under the constraint that all variables are nonnegative, and the multiplicative update rules are widely used for solving this optimization problem. In this report, we give a unified method for deriving a multiplicative update rule from a given objective function including regularization terms, and apply 22 objective functions obtained by adding two types of regularization terms to 11 error functions. |
