Abstract
We present deterministic algorithms for the uniform recovery of -variate rank one tensors from function values. These tensors are given as product of univariate functions whose th weak derivative is bounded by . The recovery problem is known to suffer from the curse of dimensionality for . For smaller , a randomized algorithm is known which breaks the curse. We construct a deterministic algorithm which is even less costly. In fact, we completely characterize the tractability of this problem by three different ranges of the parameter .
