ReMAP framework offers scalable MAP inference for arbitrary-order MRFs

Researchers have developed ReMAP, a novel framework for scalable Markov Random Field (MRF) inference. This method utilizes a Graph Neural Network to optimize a differentiable relaxation of the MRF energy, enabling gradient-based optimization in a continuous space to find low-energy discrete solutions. ReMAP supports arbitrary-order factors and heterogeneous label cardinalities, outperforming existing approximate methods and often surpassing exact solvers like Toulbar2 on challenging large-scale instances.
