报告题目:Understanding and Leveraging the Internal Representation of Convolutional Neural Networks.

报告摘要:
With the success of deep learning architectures such as convolutional neural networks (CNN) for visual processing and the access to image databases with millions of labeled examples (e.g., ImageNet, Places), the state of the art in computer vision is advancing rapidly. One important factor for continued progress is to understand the representations that are learned by the inner layers of these deep learning architectures. Here we have a comparison study to analyze the representations of the CNN trained on ImageNet for object recognition and the CNN trained on Places Database for scene recognition respectively. As scenes are composed of objects, the CNN for scene classification automatically learns to discover meaningful objects detectors. With object detectors emerging as a result of learning to recognize scenes, our work demonstrates that the same network can perform both scene recognition and object localization in a single forward-pass, without ever having been explicitly taught the notion and localization of the objects. The presentation is based on my work published in ICLR'15 and CVPR'16.
