Bayesian Reasoning Tool
Abstract
Many real problems are associated with uncertainty; the evidence people observe which helps them to reason about some goal event is almost always uncertain and incomplete. Still, people make judgements based on this uncertain and incomplete evidence. These uncertain evidences can be combined in various ways to find the validity or strength of a hypothesis, Bayesian probability theory is a normative theory that allows one to reason about and combine uncertain evidences in a way the conforms to the tenets of probability theory, but avoids the disadvantages usually associated with probabilistic computations of belief. BaRT is a Bayesian Reasoning Tool which implements Pearl's ideas. It has been implemented as an AI programming environment which can perform classification problem solving, and it has been used to classify ships. Section 2 provides an overview of the theoretical background for this work. Section 3 explains how to use BaRT and provides an example. Sections 4 and 5 provide details concerning the implementation of this system. This manual describes a preliminary version of a system which is under development. Later versions of BaRT will have greater capabilities, so any of the functions and capabilities described here are subject to change.
