On the reconstruction of functions from values at subsampled quadrature points

Felix Bartel, Lutz Kämmerer, Daniel Potts +1

This paper is concerned with function reconstruction from samples. The sampling points used in several approaches are (1) structured points connected with fast algorithms or (2) un…

Error Guarantees for Least Squares Approximation with Noisy Samples in Domain Adaptation

Felix Bartel

Given $n$ samples of a function $f : D \to C$ in random points drawn with respect to a measure $ϱ_{S}$ we develop theoretical analysis of the $L_{2} (D, ϱ_{T})$ -appr…

Constructive subsampling of finite frames with applications in optimal function recovery

Felix Bartel, Martin Schäfer, Tino Ullrich

In this paper we present new constructive methods, random and deterministic, for the efficient subsampling of finite frames in $C^{m}$ . Based on a suitable random subsampling…
