Semigroup Consistency as a Diagnostic for Learned Physics Simulators

Researchers propose semigroup consistency as a diagnostic tool to evaluate learned physics simulators by checking whether direct evolution and composed evolution produce identical results. Testing on heat and Burgers dynamics shows strong correlation between semigroup error and long-horizon rollout degradation, though using semigroup regularization as a training objective yields mixed results.

Physical Simulators as Do-Operators: Causal Discovery under Latent Confounders for AI-for-Science

Researchers introduce CFM-SD, a causal discovery method that leverages physical simulators to identify cause-and-effect relationships in scientific domains while handling latent confounders—a common problem in molecular design and materials science. The approach achieves significantly higher accuracy than existing methods and demonstrates practical improvements in real-world applications like toxicity prediction and battery optimization.
