An Order Reduction Design Framework for Higher-Order Binary Markov Random Fields [PDF]
Entropy, 2023 The order reduction method is an important approach to optimize higher-order binary Markov random fields (HoMRFs), which are widely used in information theory, machine learning and image analysis.

Learning loosely connected Markov random fields
Stochastic Systems, 2014 We consider the structure learning problem for graphical models that we call loosely connected Markov random fields, in which the number of short paths between any pair of nodes is small, and present a new conditional independence test based algorithm ...

Stroke Lesion Segmentation in FLAIR MRI Datasets Using Customized Markov Random Fields [PDF]
Frontiers in Neurology, 2019 Robust and reliable stroke lesion segmentation is a crucial step toward employing lesion volume as an independent endpoint for randomized trials. The aim of this work was to develop and evaluate a novel method to segment sub-acute ischemic stroke lesions

MRFalign: protein homology detection through alignment of Markov random fields. [PDF]
PLoS Computational Biology, 2014 Sequence-based protein homology detection has been extensively studied and so far the most sensitive method is based upon comparison of protein sequence profiles, which are derived from multiple sequence alignment (MSA) of sequence homologs in a protein ...

Locally Adaptive Smoothing with Markov Random Fields and Shrinkage Priors. [PDF]
Bayesian Anal, 2018 We present a locally adaptive nonparametric curve fitting method that operates within a fully Bayesian framework. This method uses shrinkage priors to induce sparsity in order-k differences in the latent trend function, providing a combination of local ...
