报告摘要：

Artificial intelligence and machine learning has achieved remarkable performance in extensive vision tasks such as object classification and detection. Such superior performances, however, heavily rely on a very large scale of labeled data for training, which in practice is often expensive and infeasible to obtain. Ultra-fine-grained visual categorization and visual explanation of decision-making evolution inside a model remains challenging open problems in the research community. This talk will introduce our effort towards bridging this gap, i.e., enabling image classification of very similar objects and when only few examples are available, and explaining internal attention flow of models. Some recent works such as ultra-fine-grained visual categorization beyond human performance, deep models for very similar object recognition, and attention flow will be discussed.
