The Bearable Lightness of Big Data: Towards Massive Public Datasets in Scientific Machine Learning

1 code implementation25 Jul 2022 Wai Tong Chung, Ki Sung Jung, Jacqueline H. Chen, Matthias Ihme

To illustrate this point, we demonstrate that deep learning models, trained and tested on data from a petascale CFD simulation, are robust to errors introduced during lossy compression in a semantic segmentation problem.

Interpretable Data-driven Methods for Subgrid-scale Closure in LES for Transcritical LOX/GCH4 Combustion

no code implementations11 Mar 2021 Wai Tong Chung, Aashwin Ananda Mishra, Matthias Ihme

Using this data, a priori analysis is performed on the Favre-filtered DNS data to examine the accuracy of physics-based and random forest SGS-models under these conditions.

Data-assisted combustion simulations with dynamic submodel assignment using random forests

no code implementations8 Sep 2020 Wai Tong Chung, Aashwin Ananda Mishra, Nikolaos Perakis, Matthias Ihme

In this investigation, we outline a data-assisted approach that employs random forest classifiers for local and dynamic combustion submodel assignment in turbulent-combustion simulations.
