Sharp Sobolev Sandwich and Approximation Rates of Radon-Domain $L^{p}$ Ridge Integral Spaces for ReLU $^{k}$ Networks

Juncai He, Zitong Tian

We develop the $L^{p}$ space and approximation theory for shallow neural networks with $ReLU^{k}$ activations. The central object is the Radon-domain $L^{p}$ space $\mathcal{R}L…
