摘要:

迄今为止,大多数成功的贝叶斯网络(BN)应用都是通过从专家那里获取知识来构建的,这是困难和耗时的,这导致了最近对从数据中学习BN的自动方法的兴趣。我们提出了一个案例研究,在建设BN在智能辅导应用程序,特别是十进制的误解。我们描述了BN建设使用专家启发,然后调查如何某些现有的自动化知识发现方法可能支持BN知识工程过程。

英文摘要:

Most successful Bayesian network (BN) applications to datehave been built through knowledge elicitation from experts.This is difficult and time consuming, which has lead to recentinterest in automated methods for learning BNs from data. We present a case study in the construction of a BN in anintelligent tutoring application, specifically decimal misconceptions. Wedescribe the BN construction using expert elicitation and then investigate how certainexisting automated knowledge discovery methods might support the BN knowledge engineering process.
