Physics-Informed Nonlinear Vector Autoregressive Models for the Prediction of Dynamical Systems

Abstract. Machine learning techniques have recently been of great interest for solving differential equations. Training these models is classically a data-fitting task, but knowledge of the expression of the differential equation can be used to supplement the training objective, leading to the development of physics-i...

A Unified Two-Grid Framework for Anderson Acceleration and Nonlinear GMRES

In this work, we recast two widely used acceleration methods for fixed-point iterations, Anderson acceleration (AA) and the nonlinear generalized minimal residual method (NGMRES), as two-grid methods. By explicitly deriving the error propagation matrices for AA and NGMRES on linear problems, we show that both methods,...
