对贝叶斯网及其概率推理进行了简述,提出并实现了一种以贝叶斯网为学生模型的智能教学系统,并重点介绍了学生模型的结构、功能和概率推理算法.系统运行的实例数据真实地反映了学生模型当前的解题情况.
The Bayesian network and its probabilistic reasoning are briefly described and an intelligent teaching system based on the Bayesian network is proposed and implemented. The structure, function and probability reasoning algorithm of the student model are introduced emphatically. The example data truly reflects the current problem-solving situation of the student model.
