Learning structured linear dynamical systems from missing observations

Aravinda Kanchana Ruwanpathirana, Hemant Tyagi, Sunny G. W. Wang · 2026

We consider the problem of learning structured linear dynamical systems over convex sets $\mathcal{K}$, where only a small subset of the observations are available at each time point. An estimator which minimizes a bias-corrected, potentially non-convex objective function is proposed. Non-asymptotic bounds are obtained …

RobustLDS: Learning linear dynamical systems under adversarial corruptions

Aravinda Kanchana Ruwanpathirana, Hemant Tyagi · 2026

We consider the problem of learning linear dynamical systems under adversarial contamination from a single trajectory of length $T$. While identification of linear dynamical systems itself is well-studied, the problem of robust system identification under adversarial contamination is relatively less explored. In this w …
