Researchers have introduced a novel approach called posterior-first neural PDE simulation for inferring hidden problem states from single observed fields. This method first estimates a posterior distribution over the problem state before making predictions, addressing the issue of information loss in traditional field-to-future predictors. Experiments on PDEBench tasks demonstrated that this posterior-first approach significantly reduces rollout error compared to monolithic prediction methods. AI
