Level set learning with pseudo-reversible neural networks for nonlinear dimension reduction in function approximation

2 code implementations2 Dec 2021 Yuankai Teng, Zhu Wang, Lili Ju, Anthony Gruber, Guannan Zhang

Our method contains two major components: one is the pseudo-reversible neural network (PRNN) module that effectively transforms high-dimensional input variables to low-dimensional active variables, and the other is the synthesized regression module for approximating function values based on the transformed data in the low-dimensional space.

Reduced Order Models for the Quasi-Geostrophic Equations: A Brief Survey

no code implementations1 Dec 2020 Changhong Mou, Zhu Wang, David R. Wells, Xuping Xie, Traian Iliescu

In this paper, we survey the ROMs developed for the QGE in order to understand their potential in efficient numerical simulations of more complex ocean flows: We explain how classical numerical methods for the QGE are used to generate the ROM basis functions, we outline the main steps in the construction of projection-based ROMs (with a particular focus on the under-resolved regime, when the closure problem needs to be addressed), we illustrate the ROMs in the numerical simulation of the QGE for various settings, and we present several potential future research avenues in the ROM exploration of the QGE and more complex models of geophysical flows.
