Optimal neural network approximation of smooth compositional functions on sets with low intrinsic dimension

Thomas Nagler, Sophie Langer

We study approximation and statistical learning properties of deep ReLU networks under structural assumptions that mitigate the curse of dimensionality. We prove minimax-optimal un…

Fast Rates for Nonstationary Weighted Risk Minimization

Tobias Brock, Thomas Nagler

Weighted empirical risk minimization is a common approach to prediction under distribution drift. This article studies its out-of-sample prediction error under nonstationarity. We…
