The Dynamic-Probabilistic Consistency Gap in Chaotic Surrogate Modeling
Researchers have identified a "dynamic-probabilistic consistency gap" in surrogate modeling for dynamical systems. This gap occurs when optimizing for probabilistic objectives leads to degraded system dynamics or decouples predictive uncertainty from the actual local dynamics. To address this, they propose KAFFEE, a Kalman filter-based training framework designed to improve uncertainty estimation and dynamical invariant reconstruction in chaotic systems. AI
