Uncertainty Quantification of Data-Driven Output Predictors in the Output Error Setting

no code implementations23 Apr 2024 Farzan Kaviani, Ivan Markovsky, Hamid R. Ossareh

Furthermore, our results demonstrate that applying the de-noising heuristic in the output error setup does not generally lead to a better prediction accuracy as compared to using raw data directly, nor a smaller upper bound on the prediction error.

Fast data-driven iterative learning control for linear system with output disturbance

no code implementations21 Dec 2023 Jia Wang, Leander Hemelhof, Ivan Markovsky, Panagiotis Patrinos

This paper studies data-driven iterative learning control (ILC) for linear time-invariant (LTI) systems with unknown dynamics, output disturbances and input box-constraints.

Data-based system representations from irregularly measured data

no code implementations21 Jul 2023 Mohammad Alsalti, Ivan Markovsky, Victor G. Lopez, Matthias A. Müller

Non-parametric representations of dynamical systems based on the image of a Hankel matrix of data are extensively used for data-driven control.

Adjusted least squares fitting of algebraic hypersurfaces

1 code implementation6 Dec 2014 Konstantin Usevich, Ivan Markovsky

In this paper, we present new results on invariance properties of the adjusted least squares estimator and an improved algorithm for computing the estimator for an arbitrary set of monomials in the polynomial equation.
