| 摘 要： | 模拟退火方法学习贝叶斯网络结构是一种以搜索最高得分函数为原则的智能优化方法.提出一种学习贝叶斯网络结构的限制型模拟退火方法.在该方法中,首先通过求解无约束优化问题得到一个无向图,然后使用模拟退火方法进行边及边方向的确定.由于搜索空间的规模减小,该方法比直接使用模拟退火方法学习贝叶斯网络结构的效率要高.

| Abstract: | Simulated annealing method forlearning Bayesian network structure is an intelligent optimizationmethod based on the principle of scoring function.This paper presents a constrained simulated annealing method(CSAB) to learn Bayesian network structure.In this method,an undirected graph isobtained firstly by solving an unconstrained optimization problem;then,simulated annealing method is used to determine the edge andits direction.Compared with the methods which use simulated annealing method to learn Bayesian network structure directly,asthe search space is reduced,this method is more efficiency. |
