I'm interested in the development of new formalisms and methods for artificial intelligence (AI) by combining a sound
theoretical approach with a principled experimental component. I focus on compute-intensive methods for AI.
Traditionally, general search and reasoning is largely avoided in AI by explicitly incorporating large amounts of
domain-specific knowledge. While such a knowledge-intensive approach has been successful in certain domains, such as automatic diagnosis, in other |
|
areas, such as planning or general reasoning, progress has
been disappointing. However, recent advances in general search and reasoning methods combined with faster hardware and better implementations provide strong
evidence that a compute-intensive approach is not only suitable for dealing with thecombinatorial nature of many AI formalisms,
but may also be required to supplement
domain-specific knowledge, especially
considering the knowledge-acquisition
bottleneck in terms of encoding highly
specific domain knowledge.
Part of my research is on fast general
reasoning and search techniques, with an
emphasis on stochastic methods. I also
investigate the various sources of complexity
in hard computational problems, using both
theoretical and experimental methods. This
work explores interesting connections
between computer science, artificial
intelligence, and statistical physics. In
addition, I study issues in problem
representation, including the robustness of
encodings, abstraction, compilation, and
approximation methods. These issues are
critical to the successful application in realistic
domains of reasoning and search
methods. In terms of applications, I am
particularly interested in challenge
problems from planning, knowledge
representation, machine learning, and
data mining. Our planning system,
BlackBox, developed jointly with
Henry Kautz of AT&T Laboratories,
is one of the fastest general purpose
planning systems. I also pursue
applications in areas outside AI, such
as, operations research and
software/protocol verification.
