Fourier Neural Operators with Least-Squares Readout Refit for Learning Random Obstacle-to-Solution Maps
Chenhui Zhu, Fei Wang
We study operator learning for random obstacle-to-solution maps arising from elliptic variational inequalities with finite-band self-affine random obstacle fields. Instead of intro…

Numerical Analysis of Stochastic Elliptic Variational Inequalities of the First Kind
Chenhui Zhu, Fei Wang, Weimin Han
This paper presents a numerical approach to the stochastic obstacle problem using the stochastic Galerkin (SG) method. Due to the low regularity of the solution, linear finite elem…
