Physics-Informed Diffusion Models

no code implementations21 Mar 2024 Jan-Hendrik Bastek, WaiChing Sun, Dennis M. Kochmann

We present a framework to inform denoising diffusion models on underlying constraints on such generated samples during model training.

GNN-Assisted Phase Space Integration with Application to Atomistics

no code implementations20 Mar 2023 Shashank Saxena, Jan-Hendrik Bastek, Miguel Spinola, Prateek Gupta, Dennis M. Kochmann

As a remedy, we demonstrate that Graph Neural Networks, trained on Monte-Carlo data, can serve as a replacement for commonly used numerical quadrature rules, overcoming their deficiencies and significantly improving the accuracy.

Physics-Informed Neural Networks for Shell Structures

1 code implementation26 Jul 2022 Jan-Hendrik Bastek, Dennis M. Kochmann

The numerical modeling of thin shell structures is a challenge, which has been met by a variety of finite element (FE) and other formulations -- many of which give rise to new challenges, from complex implementations to artificial locking.
