Some suggestions concerning the conjecture in: 'Tractable semi-algebraic approximation using Christoffel-Darboux kernel'
Mathias Oster, Reinhold Schneider
In 'Tractable semi-algebraic approximation using Christoffel-Darboux kernel' Marx, Pauwels, Weisser, Henrion and Lasserre conjectured, that the approximation rate $\mathcal O(\frac…
Low-rank approximation of continuous functions in Sobolev spaces with dominating mixed smoothness
Michael Griebel, Helmut Harbrecht, Reinhold Schneider
Let , , be given domains. In this article, we study the low-rank approximation with respect to of functions…
Approximation by tree tensor networks in high dimensions: Sobolev and compositional functions
Markus Bachmayr, Anthony Nouy, Reinhold Schneider
This paper is concerned with convergence estimates for fully discrete tree tensor network approximations of high-dimensional functions from several model classes. For functions hav…
Dynamical low-rank approximations of solutions to the Hamilton-Jacobi-Bellman equation
Martin Eigel, Reinhold Schneider, David Sommer
We present a novel method to approximate optimal feedback laws for nonlinear optimal control based on low-rank tensor train (TT) decompositions. The approach is based on the Dirac-…
