报告题目：Visual Recognition via Submodularity and Sparse Representation 

主持人:王瑞平(中科院计算所)

报告摘要：

Feature extraction is critical for the final performance of computer vision recognition algorithms, however, most of current prevalent features are hand-crafted, such as SIFT, HOG and LBP etc. We have developed representation learning techniques based on sparse representation and submodular functions, which can automatically learn discriminative representations from visual data. In this talk, I will firstly present a submodular learning framework for discriminative attribute selection for action recognition. Our selection framework is very general and able to achieve state-of-the-art performances. Then I will present a novel sparse representation based feature learning approach called Label Consistent K-SVD (LC-KSVD). This approach and its online learning version have been successfully applied to many other applications. Finally I will introduce a new supervised deep neural network called Label consistent Neural Network (LCNN). The class-specific representations generated by late hidden layers are discriminative enough to achieve good performance using a simple kNN classifier. The representations generated by LCNN can be directly used in other applications.
