Researchers have developed a novel nonlocal transition kernel designed to improve the efficiency and stability of learning Restricted Boltzmann Machines (RBMs). This new kernel addresses the limitations of traditional blocked Gibbs sampling (BGS), which can suffer from poor sampling quality due to its local nature, especially when RBMs have high energy barriers. The proposed method, inspired by deep tempering (DT), enables nonlocal moves within a single transition, leaving the RBM sequence invariant. Experiments indicate that this approach achieves superior sampling quality with fewer transitions compared to BGS and DT, leading to more stable learning and mitigating training failures. AI
