Our group, the Precognition Group (智能感知与预测研究组), is interested in building human-level AI systems. We focus on machine perception of human activities and the world, jointly with machine prediction of unseen future states. We believe in order to enable machines to understand and behave like humans, we should build world models with common sense knowledge that could aid intelligent agents in making action decisions. As a first step, sequential data (like that of videos) perception and prediction are important research topics to tackle.
