Learned multiphysics inversion with differentiable programming and machine learning

1 code implementation12 Apr 2023 Mathias Louboutin, Ziyi Yin, Rafael Orozco, Thomas J. Grady II, Ali Siahkoohi, Gabrio Rizzuti, Philipp A. Witte, Olav Møyner, Gerard J. Gorman, Felix J. Herrmann

We present the Seismic Laboratory for Imaging and Modeling/Monitoring (SLIM) open-source software framework for computational geophysics and, more generally, inverse problems involving the wave-equation (e. g., seismic and medical ultrasound), regularization with learned priors, and learned neural surrogates for multiphase flow simulations.

Model-Parallel Fourier Neural Operators as Learned Surrogates for Large-Scale Parametric PDEs

1 code implementation4 Apr 2022 Thomas J. Grady II, Rishi Khan, Mathias Louboutin, Ziyi Yin, Philipp A. Witte, Ranveer Chandra, Russell J. Hewett, Felix J. Herrmann

Fourier neural operators (FNOs) are a recently introduced neural network architecture for learning solution operators of partial differential equations (PDEs), which have been shown to perform significantly better than comparable deep learning approaches.

A Linear Algebraic Approach to Model Parallelism in Deep Learning

no code implementations4 Jun 2020 Russell J. Hewett, Thomas J. Grady II

We propose a linear-algebraic approach to model parallelism in deep learning, which allows parallel distribution of any tensor in the DNN.
