WebApr 2, 2014 · I would like to build a Bayesian network of discrete (pymc.Categorical) variables that are dependent on other categorical variables. As a simplest example, suppose variables a and b are categorical and b depends on a. Here is an attempt to code it with pymc (assuming a takes one of three values and b takes one of four values). The idea … WebIn this case, we will assume they are all binary. Now we are ready to make the Bayes Net. node_sizes = 2*ones(1,N); bnet = mk_bnet(dag, node_sizes); ...
