Prior specification of neighbourhood and interaction structure in binary Markov random fields
Petter Arnesen, Håkon Tjelmeland
In this paper we propose a prior distribution for the clique set and dependence structure of binary Markov random fields (MRFs). In the formulation we allow both pairwise and highe…

Fully Bayesian binary Markov random field models: Prior specification and posterior simulation
Petter Arnesen, Håkon Tjelmeland
We propose a flexible prior model for the parameters of binary Markov random fields (MRF) defined on rectangular lattices and with maximal cliques defined from a template maximal c…

Approximations and bounds for binary Markov random fields
Haakon Michael Austad, Håkon Tjelmeland
Discrete Markov random fields form a natural class of models to represent images and spatial data sets. The use of such models is, however, hampered by a computationally intractabl…
