New research defines separable graphical models for complex independence structures

A new research paper introduces the concepts of separable graphs and essentially separable graphs, which are types of graphical models used to represent complex independence structures. These models can encode relationships involving feedback, latent variables, and selection mechanisms. The paper provides multiple ways to characterize these graph types and their equivalences, including a graphical method based on ordinary graph properties and a separational characterization. Additionally, it offers a canonical representation for equivalence classes of essentially separable graphs and an algorithm for identifying them. AI
