Artificial intelligence, machine learning, automated planning and control, computer vision
My research is centered around my interest in making machines “smarter.” Machines are very far from rivaling humans in tasks such as visual understanding, planning a trip, playing real-time strategy games, language processing, tutoring, etc. Nevertheless, I believe that even small steps toward solving such tasks will yield systems that people will soon take for granted and depend on in everyday life. My general career vision is to support this progress by studying the critical computational problems that arise.
My research interests are in the artificial intelligence areas of machine learning, automated planning, and knowledge representation. I am most interested in usefully integrating these complementary areas.
One of my research thrust is to develop algorithms that can learn to interpret complex data such as videos. As an example, in the Digital Scout Project, we are studying the use of machine learning for computing interpretations of American football video. Such interpretations will allow for coaches, analysts, and fans to easily pose queries against libraries of football video for indexing and collecting statistics.
A second research thrust is to develop techniques for integrating planning and machine learning. Our work has developed new planning algorithms that can learn to solve very large problems that were beyond the scope of previous techniques. We are now extending that work to richer settings, for example, multi-agent planning, where agents must cooperate to complete a task. As a testbed we are studying planning and learning in the context of real-time strategy games, a domain where humans are currently far better than computer players.
