Learning the Factors Controlling Mineralization for Geologic Carbon Sequestration

no code implementations20 Dec 2023 Aleksandra Pachalieva, Jeffrey D. Hyman, Daniel O'Malley, Hari Viswanathan, Gowri Srinivasan

We found that the dissolution reaction rate constant of quartz and the distance to the flowing backbone in the fracture network are the two most important features that control the amount of quartz left in the system.

Reconstruction of Fields from Sparse Sensing: Differentiable Sensor Placement Enhances Generalization

no code implementations14 Dec 2023 Agnese Marcato, Daniel O'Malley, Hari Viswanathan, Eric Guiltinan, Javier E. Santos

Recreating complex, high-dimensional global fields from limited data points is a grand challenge across various scientific and industrial domains.

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.

Physics-informed machine learning with differentiable programming for heterogeneous underground reservoir pressure management

1 code implementation21 Jun 2022 Aleksandra Pachalieva, Daniel O'Malley, Dylan Robert Harp, Hari Viswanathan

To tackle this, we use differentiable programming with a full-physics model and machine learning to determine the fluid extraction rates that prevent over-pressurization at critical reservoir locations.

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.

Machine Learning in Heterogeneous Porous Materials

no code implementations4 Feb 2022 Martha D'Eli, Hang Deng, Cedric Fraces, Krishna Garikipati, Lori Graham-Brady, Amanda Howard, Geoerge Karniadakid, Vahid Keshavarzzadeh, Robert M. Kirby, Nathan Kutz, Chunhui Li, Xing Liu, Hannah Lu, Pania Newell, Daniel O'Malley, Masa Prodanovic, Gowri Srinivasan, Alexandre Tartakovsky, Daniel M. Tartakovsky, Hamdi Tchelepi, Bozo Vazic, Hari Viswanathan, Hongkyu Yoon, Piotr Zarzycki

The "Workshop on Machine learning in heterogeneous porous materials" brought together international scientific communities of applied mathematics, porous media, and material sciences with experts in the areas of heterogeneous materials, machine learning (ML) and applied mathematics to identify how ML can advance materials research.

A framework for data-driven solution and parameter estimation of PDEs using conditional generative adversarial networks

1 code implementation27 May 2021 Teeratorn Kadeethum, Daniel O'Malley, Jan Niklas Fuhg, Youngsoo Choi, Jonghyun Lee, Hari S. Viswanathan, Nikolaos Bouklas

This work is the first to employ and adapt the image-to-image translation concept based on conditional generative adversarial networks (cGAN) towards learning a forward and an inverse solution operator of partial differential equations (PDEs).

Reverse Annealing for Nonnegative/Binary Matrix Factorization

no code implementations10 Jul 2020 John Golden, Daniel O'Malley

It was recently shown that quantum annealing can be used as an effective, fast subroutine in certain types of matrix factorization algorithms.

Learning to regularize with a variational autoencoder for hydrologic inverse analysis

1 code implementation6 Jun 2019 Daniel O'Malley, John K. Golden, Velimir V. Vesselinov

A central difficulty in regularization is turning a complex conceptual model of this additional structure into a functional mathematical form to be used in the inverse analysis.
