 title: "Bayesian Structure Learning with Random Neighbourhood Samplers"
 summary: "Structure learning is of interests in many disciplines (e.g., genomics, biology, ecology, etc.) where the aim is to reconstruct a graphical model, in the form of a Directed Acyclic Graph (DAG), underlying a set of random variables. Bayesian methods have demonstrated superiority, particularly in low data regimes, for their ability to learn a distribution over possible DAGs rather than just a Maximum A Posteriori. After briefly introducing the problem of (Bayesian) structure learning, and reviewing some of the popular MCMC based approaches, we propose a novel sampler, PARNI-DAG, that performs efficient sampling from the posterior on DAGs via a locally informed, adaptive random neighbourhood proposal that results in better mixing properties. We demonstrate PARNI-DAG mixing properties and accuracy in DAG learning on a series of experimental setups."
