- Abstract:
-
The learning structure of Bayesian networks from a data set is an NP-hard problem. To deal with this problem, an artificial bee colony algorithm based on genetic operators is proposed in this paper. The structure of the Bayesian network is mapped to binary encoding, and the updated strategy of nectar is designed according to the characteristics of the Bayesian network structure. Thus the process of structure learning of the Bayesian network is transformed into the process of the bee colony finding the optimal nectar. The experimental results show that the algorithm is valid in the structure learning of Bayesian networks.
