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 satisfaction prediction are conducted to determine the correlation and influence effect between service indicators and overall satisfaction. The research findings are as follows: (1 ...
