ABSTRACT:
We look at the problem in belief revision of trying to make inferences about what an agent believed - or *will* believe - at a given moment, based on an observation of how the agent has responded to some sequence of previous belief revision inputs over time. We adopt a "reverse engineering" approach to this problem. Assuming a framework for iterated belief revision which is based on sequences, we construct a model of the agent that "best explains" the observation. Further considerations on this best-explaining model then allow inferences about the agent's epistemic behaviour to be made.
BIO:
Dr Richard Booth gained his PhD after studying with the Mathematical Logic group at Manchester University, England in 1999. After a short spell as a postdoc in the Max Planck Institute for Computer Science in Saarbruecken, Germany, he spent almost five years as a researcher at the University of Leipzig, Germany. Since November 2004 he has spent time in Australia as a postdoc, first at Wollongong University and currently at Macquarie University. Dr Booth's research interests lie in knowledge representation in general, and belief revision, uncertain reasoning, and multi-agent systems in particular.
