MetaKoopman: Bayesian Meta-Learning for Robust Dynamics Modeling

Researchers have introduced MetaKoopman, a novel Bayesian meta-learning framework designed to model nonlinear dynamics using linear latent representations. This approach learns a Matrix Normal-Inverse Wishart prior over the Koopman operator, allowing for closed-form Bayesian updates and a posterior predictive distribution that accounts for both epistemic and aleatoric uncertainty. Evaluations on an autonomous truck and trailer system in challenging winter conditions and simulated control tasks demonstrated MetaKoopman's superior performance in prediction accuracy, uncertainty calibration, and robustness to distribution shifts compared to existing methods.
