WebBayesian network (DBN). (The term “dynamic” means we are modelling a dynamic system, and does not mean the graph structure changes over time.) DBNs are quite popular because they are easy to interpret and learn: because the graph is directed, the conditional probability distribution (CPD) of each node can be estimated independently.
