WebJan 17, 2024 · Non-negative matrix factorization (NMF) is a popular and widely used method to accomplish this goal. But NMF, together with its recent, enhanced version, like graph regularized NMF or symmetric NMF, do not have the provision to include the neighborhood structure information and, as a result, may fail to provide satisfactory performance in … Webnis a given symmetric nonnegative matrix and ris the target rank. Other losses such as Kullback-Leibler divergence are possible in (NMF), but we focus here on the quadratic loss which is the most widely used. Symmetric Nonnegative Matrix Factorization (SymNMF) is a variant of NMF where the two factors are constrained to be identical.
