Another Robust NMF: Rethinking the Hyperbolic Tangent Function and Locality Constraint

IEEE Access, 2019
Non-negative matrix factorization (NMF) is a classical data analysis tool for clustering tasks. It usually considers the squared loss to measure the reconstruction error, thus it is sensitive to the presence of outliers. Looking into the literature, most
