Bayes classifier in Chapter 3 requires all the attribute variables are independent of each other. Bayesian network in this chapter allows associations among the attribute variables themselves and associations between attribute variables and target variables. Bayesian network uses associations of variables to infer information about any variable in Bayesian network. In this chapter, we first introduce the structure of a Bayesian network and the probability information of variables in a Bayesian network. Then we describe the probabilistic inference that is conducted within a Bayesian network. Finally, we introduce methods of learning the structure and probability information of a Bayesian network.
