WebbNon-negative Matrix Factorization (NMF) is a widely used algorithm for data analysis. The goal is calcula-tion a factorization of the form: X(i;j) ˇX^(i;j) = X k Z 1(i;k)Z 2(k;j) (1) where X is the given data matrix, X^ is an approxi-mation to X, and Z 1, and Z 2 are non-negative fac-tor matrices. This model has been applied to various Webb19 okt. 2024 · DDI prediction can be viewed as a matrix completion task, for which matrix factorization (MF) appears as a suitable solution.
