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. In this WebBayesian Networks, the result of the convergence of artificial intelligence with statistics, are growing in popularity. Their versatility and modelling power is now employed across a variety of fields for the purposes of analysis, simulation, prediction and diagnosis.
