Efficient machine-learning surrogates for large-scale geological carbon and energy storage

no code implementations11 Oct 2023 Teeratorn Kadeethum, Stephen J. Verzi, Hongkyu Yoon

Geological carbon and energy storage are pivotal for achieving net-zero carbon emissions and addressing climate change.

Progressive reduced order modeling: empowering data-driven modeling with selective knowledge transfer

no code implementations4 Oct 2023 Teeratorn Kadeethum, Daniel O'Malley, Youngsoo Choi, Hari S. Viswanathan, Hongkyu Yoon

Data-driven modeling can suffer from a constant demand for data, leading to reduced accuracy and impractical for engineering applications due to the high cost and scarcity of information.

Subsurface Characterization using Ensemble-based Approaches with Deep Generative Models

1 code implementation2 Oct 2023 Jichao Bao, Hongkyu Yoon, Jonghyun Lee

WGAN-GP is trained to generate high-dimensional K fields from a low-dimensional latent space and ES-MDA then updates the latent variables by assimilating available measurements.

Reduced order modeling for flow and transport problems with Barlow Twins self-supervised learning

no code implementations11 Feb 2022 Teeratorn Kadeethum, Francesco Ballarin, Daniel O'Malley, Youngsoo Choi, Nikolaos Bouklas, Hongkyu Yoon

Through a series of benchmark problems of natural convection in porous media, BT-AE performs better than the previous DL-ROM framework by providing comparable results to POD-based approaches for problems where the solution lies within a linear subspace as well as DL-ROM autoencoder-based techniques where the solution lies on a nonlinear manifold; consequently, bridges the gap between linear and nonlinear reduced manifolds.

Fast and Scalable Earth Texture Synthesis using Spatially Assembled Generative Adversarial Neural Networks

no code implementations13 Nov 2020 Sung Eun Kim, Hongkyu Yoon, Jonghyun Lee

The earth texture with complex morphological geometry and compositions such as shale and carbonate rocks, is typically characterized with sparse field samples because of an expensive and time-consuming characterization process.
