Recovery algorithms for high-dimensional rank one tensors

David Krieg, Daniel Rudolf

We present deterministic algorithms for the uniform recovery of $d$ -variate rank one tensors from function values. These tensors are given as product of $d$ univariate functions wh…

Optimal Monte Carlo Methods for $L^{2}$ -Approximation

David Krieg

We construct Monte Carlo methods for the $L^{2}$ -approximation in Hilbert spaces of multivariate functions sampling no more than $n$ function values of the target function. Their err…
