报告题目： Research of Theories and Methods of Pattern Classification and Dimensionality Reduction

主持人：王楠楠（西安电子科技大学）

报告摘要：

In this webinar, we will introduce some progresses in classification and dimensionality reduction: 

1. Classification：A novel pattern classification framework, namely, representative vector machines (or RVMs for short) are proposed in [1]. The basic idea of RVMs is to assign the class label of a test example according to its nearest representative vector. The proposed RVMs establish a unified framework of classical classifiers because the nearest neighbor (NN) classifier, the nearest feature line (NFL) classifier, the nearest feature plane (NFP) classifier, the nearest centroid (NC) classifier, nearest feature space (NFS) classifier, support vector machine (SVM), and sparse representation-based classification (SRC) can be interpreted as the special cases of RVMs with different definitions of representative vectors.

2. Dimensionality reduction: feature selection. A comprehensive survey of feature selection based on structured sparsity is given in [2]. This paper [2] is a survey on sparse representation with its applications in feature selection.

3. Dimensionality reduction: feature extraction [3]. How to automatically estimate the optimal regularization parameter of spectral regression discriminant analysis (SRDA) is proposed in [3].
