Research on large margin classifiers from the "local" and "global" view has become an active topic in machine learning and pattern recognition. Inspired from the typical local and global learning machine Maxi-Min Margin Machine (M4) and the idea of the Locality Preserving Projections (LPP), we propose a novel large margin classifier, the Generalized Locality Preserving Maxi-Min Margin Machine (GLPM), where the within-class matrices are constructed using the labeled training points in a supervised way, and then used to build the classifier. The within-class matrices of GLPM preserve the intra-class manifold in the training sets, as well as the covariance matrices which indicate the global projection direction in the M4model. Moreover, the connections among GLPM, M4and LFDA are theoretically analyzed, and we show that GLPM can be considered as a generalized M4machine. The GLPM is also more robust since it requires no assumption on data distribution while Gaussian data distribution is assumed in the M4machine. Experiments on data sets from the machine learning repository demonstrate its advantage over M4in both local and global learning performance.
