In this paper, we extend the Fisher nonnegative matrix factorization (FNMF) to weighted FNMF (WFNMF). The goal of this technique is to improve the performance of FNMF-based face recognition method under varying expressions, varying illumination, and especially for the case of partial occlusions. An objective function is defined by incorporating weighting into the cost of FNMF decomposition in order...
Chinese Web page classification (WPC) has been considered as a hot research area in data mining. In order to effectively classify Web pages, we present a Web page categorization based on a least square support vector machine (LS-SVM) with latent semantic analysis (LSA). LSA uses singular value decomposition (SVD) to obtain latent semantic structure of original term-document matrix solving the polysemous...
