PPT-Bayesian Belief Networks

Structure and Concepts DSeparation How do they compute probabilities How to design BBN using simple examples Other capabilities of Belief Network Netica Demo short Example 2 BN probability of a variable only depends on its direct successors . Bayesian Network Motivation. We want a representation and reasoning system that is based on conditional . independence. Compact yet expressive representation. Efficient reasoning procedures. Bayesian Networks are such a representation. Read R&N Ch. 14.1-14.2. Next lecture: Read R&N 18.1-18.4. You will be expected to know. Basic concepts and vocabulary of Bayesian networks..
