本文提出了一种从数据库构建概率网络的贝叶斯方法。特别是，我们专注于构建贝叶斯信念网络。潜在的应用包括计算机辅助假设检验、自动化科学发现和概率专家系统的自动化构建。我们扩展了基本方法来处理缺失数据和隐藏（潜在）变量。我们展示了如何通过对多个信念网络的推理进行平均来执行概率推理。给出了从案例数据库构建信念网络的算法的初步评估结果。最后，我们将本文中的方法与之前的工作联系起来，并讨论开放问题。
This paper presents a Bayesian method for constructing probabilistic networks from databases. In particular, we focus on constructing Bayesian belief networks. Potential applications include computer-assisted hypothesis testing, automated scientific discovery, and automated construction of probabilistic expert systems. We extend the basic method to handle missing data and hidden (latent) variables. We show how to perform probabilistic inference by averaging over the inferences of multiple belief networks. Results are presented of a preliminary evaluation of an algorithm for constructing a belief network from a database of cases. Finally, we relate the methods in this paper to previous work, and we discuss open problems.
