Greedy equivalence search ges

WebWe introduce Selective Greedy Equivalence Search (SGES), a restricted version of Greedy Equivalence Search (GES). SGES retains the asymptotic correctness of GES but, unlike GES, has polynomial performance guarantees. In particular, we show that when data are sampled independently from a distribution that is perfect with respect to a DAG G … WebDec 28, 2024 · GES (greedy equivalence search) is a score-based algorithm that greedily maximizes a score function (typically the BIC, passed to the function via the argument …

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. WebFeb 1, 2024 · GES (Greedy Equivalence Search) [4] is a data-driven score plus search structural BN learning algorithm that carries out the search in the space of DAG equivalence classes. As mentioned in previous sections, equivalence classes are represented by using a mixed graph structure which contains directed and undirected …

GES is a Bayesian algorithm that heuristically …

Webscore via greedy approaches. An example is the prominent Greedy Equivalence Search (GES) [14]. Hybrid methods either alternate between score-based and constraint-based updates, as in Max-Min Hill-Climbing [26], or use score functions based on CI tests, as in the recently introduced Greedy SP algorithm [23].
