无圈有向混合图的一个因子分解准则

A factorization criterion for acyclic directed mixed graphs

University of Washington(华盛顿大学)

Thomas S. Richardson

摘要:

无环有向混合图,也称为半马尔可夫模型,表示由具有潜在变量的DAG模型在观察到的边缘上诱导的条件独立结构。在本文中,我们提出了一个因式分解标准,这些模型是等价的全球马尔可夫性质(自然扩展)d-分离。

英文摘要:

Acyclic directed mixed graphs, also known as semi-Markov models represent the conditional independence structure induced on an observed margin by a DAG model with latent variables. In this paper we present a factorization criterion for these models that is equivalent to the global Markov property given by (the natural extension of) d-separation.
