Learning Markov equivalence classes of Bayesian Network with immune genetic algorithm
Haiyang Jia, Dayou Liu, Juan Chen, Jinghua Guan · 2008
Bayesian Networks is a popular tool for representing uncertainty knowledge in artificial intelligence fields. Learning BNs from data is helpful to understand the casual relation between variables. But Learning BNs is a NP hard problem. This paper presents an immune genetic algorithm for learning Markov equivalence classes, which combining dependency analysis and search-scoring approach together. Experiments show that the immune operators can constrain the search space and improve the computational performance.
