ABSTRACT:Bayesian Artificial Intelligence is the incorporation of Bayesian inferential methods in the development of a software
architecture for an artificial intelligence(AI). We believe that important ingredients of such an architecture will be Bayesian
networks and the Bayesian learning of Bayesian networks from observation and experiment. In this talk, we show the elements of
Bayesian network technology, automated causal discovery, learning probabilities from data, and examples and ideas about how to
employ these technologies in developing data-mining tool. Especially, this talk emphasizes the importance of the variable
selection to build effective and meaningful causal models, and introduce some new methods of variable selection methods for
Bayesian networks.
