Abstract: We develop Splitting Factor Analysis (SFA), a novel linear model selection technique for dimension reduction that seeks to optimize the discriminative ability of the nearest neighbor classifier for data classification and labeling. We also discuss methodology for data kernelization that can be used in conjunction with any model selection technique. Applied to SFA, it leads to KSFA, a powerful new technique for the analysis of datasets with essential nonlinearities underlying their structures. For computational efficiency in the analysis of large datasets, we combine weak KSFA classifiers with multi-class boosting techniques. Several applications to image-based classification are discussed.
