Bayesian network (or Bayesian network, belief network) is a graph probabilistic model, which is a set of variables and their probabilistic dependencies according to Bayes. Formally, a Bayesian network is a directed acyclic graph, each vertex of which corresponds to a random variable, and the arcs of the graph encode conditional independence relations between these variables.
