摘要:

有希望的结果已经推动了最近的兴趣激增,从观测数据中学习贝叶斯网络结构的连续优化方法。然而,仅从观测数据获得的潜在结构的可识别性存在理论上的限制。介入数据提供了关于基本数据生成过程的更丰富的信息。然而,扩展和应用为观测数据设计的方法以包括干预措施并不简单,仍然是一个悬而未决的问题。在本文中,我们提供了一个通用的框架,基于连续优化和神经网络创建模型的组合观察和干预数据。所提出的方法甚至适用于具有挑战性和现实的情况下,干预后的变量是未知的。我们研究所提出的方法,在设置图恢复从头和从一个部分已知的边缘集。我们建立了强大的基准测试结果的几个结构学习任务,包括结构恢复的合成图以及标准图的贝叶斯网络知识库。

英文摘要:

Promising results have driven a recent surge of interest in continuous optimization methods for Bayesian network structure learning from observational data. However, there are theoretical limitations on the identifiability of underlying structures obtained from observational data alone. Interventional data provides much richer information about the underlying data-generating process. However, the extension and application of methods designed for observational data to include interventions is not straightforward and remains an open problem. In this paper we provide a general framework based on continuous optimization and neural networks to create models for the combination of observational and interventional data. The proposed method is even applicable in the challenging and realistic case that the identity of the intervened upon variable is unknown. We examine the proposed method in the setting of graph recovery both de novo and from a partially-known edge set. We establish strong benchmark results on several structure learning tasks, including structure recovery of both synthetic graphs as well as standard graphs from the Bayesian Network Repository.
