WebJun 1, 2013 · Greedy Equivalence Search (GES) is nowadays the state of the art algorithm for learning Bayesian networks (BNs) from complete data. However, from a practical … WebGES is a Bayesian algorithm that heuristically searches the space of CBNs and returns the model with highest score it finds. In particular, GES starts its search with the empty graph. It then performs a forward stepping search in which edges are added between nodes in order to increase the Bayesian score.
