Fitting a manifold to data in the presence of large noise

Charles Fefferman, Sergei Ivanov, Matti Lassas +1

We assume that $M_{0}$ is a $d$ -dimensional $C^{2, 1}$ -smooth submanifold of $R^{n}$ . Let $K_{0}$ be the convex hull of $M_{0},$ and $B_{1}^{n} (0)$ be the unit ball. We assume that $ M_0 \subse…

Controlling Unknown Linear Dynamics with Almost Optimal Regret

Jacob Carruth, Maximilian F. Eggl, Charles Fefferman +1

Here and in a companion paper, we consider a simple control problem in which the underlying dynamics depend on a parameter $a$ that is unknown and must be learned. In this paper, w…

Optimal Agnostic Control of Unknown Linear Dynamics in a Bounded Parameter Range

Jacob Carruth, Maximilian F. Eggl, Charles Fefferman +1

Here and in a follow-on paper, we consider a simple control problem in which the underlying dynamics depend on a parameter $a$ that is unknown and must be learned. In this paper, w…
