报告摘要：Automatically recognizing objects, scenes and actions is a core component of an artificial intelligence system. In this talk, I will cover two of my main research areas – human action recognition and deep learning. Action recognition has been an active research topic in computer vision due to its various applications in human-machine interaction, robotics, video surveillance and visual big data search. I will first review some related work on handcrafted features, feature/deep learning and attributes learning. Then I will introduce our recent multi-task system that can jointly solve three main problems: 1) Where in the video do the actions occur? (2) What categories do the actions belong to? and (3) How are these actions performed? This multi-task learning framework is designed based on a state-of-the-art 3D deep convolutional neural network (3D-CNN). Specifically, in the training phase, action localization, classification and attributes learning can be jointly optimized via the proposed deep architecture. Once model training is completed, given an upcoming test video, we can describe each individual action in the video simultaneously as: where the action occurs, what the action is and how the action is performed. To train the deep network, we also introduce a new large-scale aligned action dataset, NASA, with 200K well labeled video clips. Finally, I will present the results of detailed action parsing on challenging, realistic datasets that are collected by us or publicly available. Some initial results on zero-shot learning via the obtained action attributes will be discussed too.
