Data-Driven Autoencoder Numerical Solver with Uncertainty Quantification for Fast Physical Simulations

1 code implementation2 Dec 2023 Christophe Bonneville, Youngsoo Choi, Debojyoti Ghosh, Jonathan L. Belof

Traditional partial differential equation (PDE) solvers can be computationally expensive, which motivates the development of faster methods, such as reduced-order-models (ROMs).

GPLaSDI: Gaussian Process-based Interpretable Latent Space Dynamics Identification through Deep Autoencoder

1 code implementation10 Aug 2023 Christophe Bonneville, Youngsoo Choi, Debojyoti Ghosh, Jonathan L. Belof

By interpolating and solving the ODE system in the reduced latent space, fast and accurate ROM predictions can be made by feeding the predicted latent space dynamics into the decoder.

Certified data-driven physics-informed greedy auto-encoder simulator

1 code implementation24 Nov 2022 Xiaolong He, Youngsoo Choi, William D. Fries, Jonathan L. Belof, Jiun-Shyan Chen

A parametric adaptive greedy Latent Space Dynamics Identification (gLaSDI) framework is developed for accurate, efficient, and certified data-driven physics-informed greedy auto-encoder simulators of high-dimensional nonlinear dynamical systems.

Using Conservation Laws to Infer Deep Learning Model Accuracy of Richtmyer-meshkov Instabilities

no code implementations19 Jul 2022 Charles F. Jekel, Dane M. Sterbentz, Sylvie Aubry, Youngsoo Choi, Daniel A. White, Jonathan L. Belof

Richtmyer-Meshkov Instability (RMI) is a complicated phenomenon that occurs when a shockwave passes through a perturbed interface.
