      Chain rule : the chain rule is an extension of the product rule which we can write down in more generic form as: Bayes’ rule: Bayes’ rule is an alternative method to calculate the conditional probability if the joint probability is unknown. From the conditional probability, we know as well as. Bayes rule is

      The Bayesian methodology is built upon the well known Bayes’ Rule, which is itself derived from the fundamental rule for probability calculus. (1) In Equation 1, P(a,b) is the joint probability of both events a and b occurring, P(a|b) is the conditional probability of event a occurring given that event b occurred, and P(b) is the probability ...

      The Bayes nets effectively weight the precision of each rule either individually or based on the outcome of another rule in the case of TAN. The Bayesian nets further combine these probabilities to make a prediction of the final classification allowing them to discount the influence of spurious rules in the classification process.

      This is a relatively straightforward application of Bayes’ rule. Let Y = Y1, …, yl be the children of Xi and let Zj be the parents of yj other than Xi. Then we have where the derivation of the third line from the second relies on the fact that a node is independent of its non-descendants given its children.
