Rate-Optimal Non-Asymptotics for the Quadratic Prediction Error Method

no code implementations11 Apr 2024 Charis Stamouli, Ingvar Ziemann, George J. Pappas

We study the quadratic prediction error method -- i. e., nonlinear least squares -- for a class of time-varying parametric predictor models satisfying a certain identifiability condition.

Structural Risk Minimization for Learning Nonlinear Dynamics

no code implementations28 Sep 2023 Charis Stamouli, Evangelos Chatzipantazis, George J. Pappas

We empirically show that even though too loose to be used as absolute estimates, our SRM bounds on the true prediction error are able to track its relative behavior across different model classes of the hierarchy.

Adaptive Stochastic MPC under Unknown Noise Distribution

no code implementations3 Apr 2022 Charis Stamouli, Anastasios Tsiamis, Manfred Morari, George J. Pappas

Then, we employ this benchmark controller to derive a novel robustly stable adaptive SMPC scheme that learns the necessary noise statistics online, while guaranteeing time-uniform satisfaction of the unknown reformulated state constraints with high probability.
