On the Partition Function and Random Maximum A-Posteriori Perturbations
by Tamir Hazan, Tommi Jaakkola at ICML 2012
n this paper we relate the partition function to the max-statistics of random variables. In particular, we provide a novel framework for approximating and bounding the partition function using MAP inference on randomly perturbed models. As a result, we can directly use efficient MAP solvers such as graph-cuts to evaluate the corresponding partition function. We show that our method excels in the typical ``high signal - high coupling'' regime that results in ragged energy landscapes difficult for alternative approaches.
