WebMar 18, 2024 · The Greedy Thick Thinning algorithm was used for the structural learning phase of the model construction. This algorithm is based on the Bayesian Search approach [ 53 ] . In the thickening phase, it begins with an empty graph and iteratively adds the next arc that maximally increases the marginal likelihood of the data given the model. WebFirst, a Bayesian network (BN) is constructed by integrating the greedy thick thinning (GTT) algorithm with expert knowledge. Then, sensitivity analysis and overall …
WebGreedy Thick Thinning¶ This learning algorithm uses the Greedy Thick Thinning procedure. It is a general-purpose graph structure learning algorithm, meaning it will attempt to search the full space of graphs for the best graph. The probability tables are filled out using Expectation Maximization.
