Truncation Dimension for Function Approximation

10 Oct 2016 Kritzer Peter Pillichshammer Friedrich Wasilkowski G. W.

We consider approximation of functions of $s$ variables, where $s$ is very large or infinite, that belong to weighted anchored spaces. We study when such functions can be approximated by algorithms designed for functions with only very small number ${\rm dim^{trnc}}(\varepsilon)$ of variables... (read more)
