Query: Structure Learning of Contextual Markov Networks using Marginal
  Pseudo-likelihood   Markov networks are popular models for discrete multivariate systems where
the dependence structure of the variables is specified by an undirected graph.
To allow for more expressive dependence structures, several generalizations of
Markov networks have been proposed. Here we consider the class of contextual
Markov networks which takes into account possible context-specific
independences among pairs of variables. Structure learning of contextual Markov
networks is very challenging due to the extremely large number of possible
structures. One of the main challenges has been to design a score, by which a
structure can be assessed in terms of model fit related to complexity, without
assuming chordality. Here we introduce the marginal pseudo-likelihood as an
analytically tractable criterion for general contextual Markov networks. Our
criterion is shown to yield a consistent structure estimator. Experiments
demonstrate the favorable properties of our method in terms of predictive
accuracy of the inferred models.
