From: Gideon Sahar <gideon%edai.edinburgh.ac.uk@cs.ucl.ac.uk> EDINBURGH AI SEMINARS Date: Wednesday, 19th February l9986 Time: 2.00 p.m. Place: Department of Artificial Intelligence Seminar Room Forrest Hill EDINBURGH. Dr. Robert C. Moore, Computer Laboratory, University of Cambridge (visiting from SRI International) will give a seminar entitled - "The Architecture of a Rational Agent". The ultimate goal of artificial intelligence is to build complete, autonomous, artificial rational agents. Most research in AI focuses on one or another component of such an agent: the vision sybsystem, reasoning subsystem, language subsystem, etc. Recently, however, some attention has begun to be paid to the over-all architecture in which these subsystems are combined. The first half of this talk will discuss how concern for the architecture of rational agents is motivated by the need to treat language as a form of rational action, and how this view of language provides a formal framework for treating phenomena that have been argued to be beyond the scope of formal analysis. In the second half of the talk, we will compare the three component belief/desire/intention model of rational agency typically used in AI to the two component model cannot satisfactorily account for cooperation among rational agents, proving a theorem to the effect that there are situations in which there is no strategy for a group of two-component agents that is rational by the normal standards of decision theory.
