My research interests are in the areas of machine learning and computer vision. Specifically, I have some practical experience on large scale video analysis and vision-language embedding area like visual question answering. Before I came to US, I have worked in Microsoft Research Asia and Baidu Institute of Deep Learning, our team won the 1st place for ActivityNet kinetics challenges and 3rd place for google cloud and Youtube-8m large scale video understanding challenges which are golden competitions in action recognition area. More recently, I explore the reinforcement learning for sequential model on video summarization.
