Limited-Memory Fast Gradient Descent Method for Graph Regularized Nonnegative Matrix Factorization
Graph regularized nonnegative matrix factorization (GNMF) decomposes a nonnegative data matrix [Image: see text] to the product of two lower-rank nonnegative factor matrices, i.e., [Image: see text] and [Image: see text] ([Image: see text]) and aims to preserve the local geometric structure of the d...
