T U T O R I A L DEPARTMENT OF STATISTICS AND ACTUARIAL SCIENCE UNIVERSITY OF WATERLOO SPEAKER: Dr. David Spiegelhalter Medical Research Council Cambridge University TITLE: An Introduction to Statistical Methods in Expert Systems ABSTRACT An overview of the probabilistic representation of uncertainty in expert systems will be provided. Topics will include the inadequacy of rule-based systems, the use of acyclic directed graphs to express conditional independence, directed Markov models, computational algorithms based on local message-passing, Markov field representations, relation between a triangulated graph and a clique-tree, simple message-passing solution, updating conditional probabilities from data, eliciting initial models, and so on. The talk will be reasonably non-technical, and will concentrate on imparting a feel for the area with the aid of practical problems. DATE: Friday, March 17, 1989 TIME: 10:30 a.m. PLACE: MC 5158
