Universal $L_{2}$ -approximation using median lattice algorithms

Zexin Pan, Takashi Goda, Peter Kritzer

We study the problem of multivariate $L_{2}$ -approximation of functions in a weighted Korobov space using a median lattice-based algorithm recently proposed by the authors. In the or…

$L_{2}$ -approximation using median lattice algorithms

Zexin Pan, Peter Kritzer, Takashi Goda

In this paper, we study the problem of multivariate $L_{2}$ -approximation of functions belonging to a weighted Korobov space. We propose and analyze a median lattice-based algorithm,…
