Structural Learning of Bayesian networks (BNs) is an NP-hard problem generally addressed by means of heuristic search algorithms.
One of these approaches for structural learning consists of searching the space of orderings, as given a certain topological order among the problem variables, ...
In this study, the scoring and searching task is implemented in the complete node ordering space, and a novel neighbor operation is proposed for improving ...
This article proves the correctness of the method used to evaluate each ordering, and proposes some efficient learning algorithms based on it that are based ...
There are generally three main approaches to the BNSL problem: score-based , constraint-based and hybrid learning. We propose a new simple and fast algorithm ...
This study proposed two partition constraints—ancestral and heuristic partition—to improve the efficiency of exact learning algorithms.
