贝叶斯网络学习:离散域和高斯域的统一
Learning Bayesian Networks: A Unification for Discrete and Gaussian Domains
摘要:
我们研究贝叶斯方法学习贝叶斯网络的先验知识和统计数据的组合。特别是,我们统一的方法,我们在去年的会议上提出的离散和高斯域。我们推导出一个一般的贝叶斯评分指标,适用于这两个领域。然后,我们使用这个度量结合著名的统计事实的Dirichlet和正常的Wishart分布,以获得我们的度量离散和高斯域。
英文摘要:
We examine Bayesian methods for learning Bayesian networks from a combination of prior knowledge and statistical data. In particular, we unify the approaches we presented at last year's conference for discrete and Gaussian domains. We derive a general Bayesian scoring metric, appropriate for both domains. We then use this metric in combination with well-known statistical facts about the Dirichlet and normal--Wishart distributions to derive our metrics for discrete and Gaussian domains.
