Abstract
In the last 10 years, the combination of techniques from machine learning and
operations research has allowed major advances in learning and planning for
uncertain environments. Reasonably large problems can be solved using current
techniques. But what if we want to scale up to the uncertain learning and
planning problem that you face every day? It is many orders of magnitude
larger than the biggest problem we can solve currently.
In this talk, I'll describe three early pieces of work that try to begin to
address working in truly huge environments. The first is a method for learning
probabilistic rules to describe naive physics models of the interactions
between objects. The second is an uncertain planning algorithm that uses the
rules learned by the first method to construct contingency plans that consider
enough cases to perform robustly, but are much smaller than complete policies.
The last piece is preliminary work on combining multiple abstraction methods
dynamically, in order to allow an agent to have a working model of the
environment that changes focus depending on the current situation.
About the Speaker
Leslie Pack Kaelbling is Professor of Computer Science and Engineering and a
Research Director of the Computer Science and Artificial Intelligence
Laboratory (CSAIL) at the Massachusetts Institute of Technology. She has
previously held positions at Brown University, the Artificial Intelligence
Center of SRI International, and at Teleos Research. She received an A. B. in
Philosophy in 1983 and a Ph. D. in Computer Science in 1990, both from Stanford
University. Prof. Kaelbling has done substantial research on designing
situated agents, mobile robotics, reinforcement learning, and
decision-theoretic planning. In 2000, she founded the Journal of Machine
Learning Research, a high-quality journal that is both freely available
electronically as well as published in archival form; she currently serves as
editor-in-chief. Prof. Kaelbling is an NSF Presidential Faculty Fellow, a
former member of the AAAI Executive Council, the 1997 recipient of the IJCAI
Computers and Thought Award, a trustee of IJCAII and a fellow of the AAAI.
