Numerical wave propagation aided by deep learning
Hieu Nguyen, Richard Tsai
We propose a deep learning approach for wave propagation in media with multiscale wave speed, using a second-order linear wave equation model. We use neural networks to enhance the…

A stable parareal-like method for the second order wave equation
Hieu Nguyen, Richard Tsai
A new parallel-in-time iterative method is proposed for solving the homogeneous second-order wave equation. The new method involves a coarse scale propagator, allowing for larger t…

θ-parareal schemes
Gil Ariel, Hieu Nguyen, Richard Tsai
A weighted version of the parareal method for parallel-in-time computation of time dependent problems is presented. Linear stability analysis for a scalar weighing strategy shows t…
