Remarks
MatrixFactorizationModelParameters stores two factor matrices, P and Q, for approximating the training matrix, R, by P * Q, where * is a matrix multiplication. This model expects two inputs, row index and column index, and produces the (approximated) value at the location specified by the two inputs in R. More specifically, if input row and column indices are u and v, respectively. The output (a scalar) would be the inner product of the u-th row in P and the v-th column in Q.
