Structure and Concepts DSeparation How do they compute probabilities How to design BBN using simple examples Other capabilities of Belief Network Netica Demo short Develop a BBN for HD . (Belief:) It is going to rain. So, (Belief:) The streets will get wet. When I say that this process an end, and that we can reach more specific conclusions about which actions we have an obligati 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..
