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.
