报告摘要: Decomposing the dictionary into some sub-dictionaries with different properties would greatly boost the performance of sparse representation many computer vision tasks. In this report, I will present two algorithms for multi-dictionaries based sparse representation as well as their applications, including fine-grained image categorization and one-shot face recognition.

报告摘要: Attribute learning is emerged as a promising paradigm for bridging the semantic gap and addressing data sparsity via transferring attribute knowledge in image object recognition and relatively simple human action classification. However, attributes are very limited in understanding more complex image/video classes. In this talk, I will introduce our approaches for generalising the previous attribute learning framework to transductive multi-view semantic embedding for zero-shot learning. Specifically, we identify and solve three challenging problems in canonical zero-shot learning pipeline, i.e. projection domain shift problem, prototype sparsity problem and multiple semantic representations embedding problem. Our framework greatly improves the zero-shot learning accuracy on several benchmark dataset.
报告人简介: Yanwei Fu received the PhD degree from Queen Mary University of London in 2014, and the MEng degree from the Department of Computer Science & Technology, Nanjing University in 2011, China. He is a postdoctoral researcher with Leonid Sigal in Disney Research, Pittsburgh, which is co-located with Carnegie Mellon University. His research interests include image and video understanding and description, robust ranking and learning to rank, and large-scale surveillance video analysis.
