A unconditionally energy dissipative, adaptive IMEX BDF2 scheme and its error estimates for Cahn-Hilliard equation on generalized SAV approach
Yifan Wei, Jiwei Zhang, Chengchao Zhao +1
An adaptive implicit-explicit (IMEX) BDF2 scheme is investigated on generalized SAV approach for the Cahn-Hilliard equation by combining with Fourier spectral method in space. It i…

A priori generalization error for two-layer ReLU neural network through minimum norm solution
Zhi-Qin John Xu, Jiwei Zhang, Yaoyu Zhang +1
We focus on estimating \emph{a priori} generalization error of two-layer ReLU neural networks (NNs) trained by mean squared error, which only depends on initial parameters and the…
