Vito: Vision transformer-operator

O Ovadia, A Kahana, P Stinis, E Turkel, D Givoli… - Computer Methods in …, 2024 - Elsevier
We combine vision transformers with operator learning to solve diverse inverse problems
described by partial differential equations (PDEs). Our approach, named Vision Transformer …

A convolutional dispersion relation preserving scheme for the acoustic wave equation

O Ovadia, A Kahana, E Turkel - Applied Mathematics and Computation, 2024 - Elsevier
We propose a numerical scheme for approximating the solution of the two dimensional
acoustic wave problem. We use machine learning to find a stencil suitable even for high …
