Some p-robust a posteriori error estimates based on auxiliary spaces

Yuwen Li

This work develops polynomial-degree-robust (p-robust) equilibrated a posteriori error estimates for $H (curl)$ , $H (div)$ and $H (divdiv)$ problems, based on $H^{1}$ auxili…

Some Super-approximation Rates of ReLU Neural Networks for Korobov Functions

Yuwen Li, Guozhi Zhang

This paper examines the $L_{p}$ and $W_{p}^{1}$ norm approximation errors of ReLU neural networks for Korobov functions. In terms of network width and depth, we derive nearly optimal sup…

Higher Order Approximation Rates for ReLU CNNs in Korobov Spaces

Yuwen Li, Guozhi Zhang

This paper investigates the $L_{p}$ approximation error for higher order Korobov functions using deep convolutional neural networks (CNNs) with ReLU activation. For target functions…
