A factorization criterion for acyclic directed mixed graphs (1406.6764v1)
Published 26 Jun 2014 in cs.AI
Abstract: 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.
