题目:Discriminative Subspace Selection: Problems, Solutions and Applications判决子空间选择:问题,方法及应用

报告人:陶大成博士

报告摘要:

Discriminative subspace selection (DSS) is a powerful tool in machine learning. The past decades has witnessed the effectiveness and the efficiency of DSS for subsequent classification and data visualization. In this talk, we start from the most conventional DSS algorithm, Fisher's linear discriminant analysis (FLDA). Afterwards, we enumerate FLDA's problems, i.e., the heteroscedastic problem, the multimodal problem, the class

separation problem, the under sampled problem, the data nonlinearlity, and the sample selection bias. It is worth emphasizing that all DSS algorithms share some of these problems, so it is essential to find general solutions to them. In particular, we recently present five frameworks, i.e., the general averaged divergence analysis, the general tensor discriminant analysis, the patch alignment framework, the ensemble manifold regularization, and the Bregman divergence based regularization, to address or at least reduce the aforementioned problems. Thorough experimental evidence on various real datasets and artificial datasets suggests these frameworks are effective to deal with popular DSS problems.
