Nonlinear approximation in bounded orthonormal product bases

Lutz Kämmerer, Daniel Potts, Fabian Taubert

We present a dimension-incremental algorithm for the nonlinear approximation of high-dimensional functions in an arbitrary bounded orthonormal product basis. Our goal is to detect…

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…
