WebJun 6, 2015 · Download PDF Abstract: We 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 … WebNP-complete (Chickering, 1995), the optimization is usually performed greedily such as in the prominent Greedy Equivalence Search (GES ) (Chickering, 2002). Finally, hybrid methods have also been considered; Max-Min Hill-Climbing (MMHC ) (Tsamardinos et al., 2006), for example, alternates between constraint- and score-based updates.

Webdata. Score-based algorithms, such as greedy equivalence search (GES) (Chickering,2002), maximize a particular score function over the space of graphs. Hybrid algorithms such as greedy sparsest permutation (GSP) combine ele-ments of both methods (Solus et al.,2024). Algorithms have also been developed to learn causal graphs WebJan 4, 2024 · For example, the greedy equivalence search (Chickering, 2002; see also the 1997, PhD thesis by C. Meek from the Carnegie Mellon University) ... In the oracle and low-dimensional settings, the greedy equivalence search, denoted GES in all figures, was simulated using the Bayesian information criterion. In the high-dimensional setting, ...
WebCenter for Causal Discovery Websearch algorithms can be shown to achieve global optimality in the large sample limit even with a relatively sparse search space. One of the best-known procedures of this kind is Greedy Equivalence Search (GES) [Chickering, 2002]. The standard score-based GES algorithm requires a scor-ing criterion to evaluate each candidate graph. Classical

(2016) introduced GFCI (Greedy FCI), which is a hybrid score-based algorithm that combines features of the Greedy Equivalence Search (GES, Chickering, 2002) with FCI.
