Recurrent Convolutional Deep Neural Networks for Modeling Time-Resolved Wildfire Spread Behavior

no code implementations28 Oct 2022 John Burge, Matthew R. Bonanni, R. Lily Hu, Matthias Ihme

While deep learning approaches have demonstrated the ability to predict wildfire propagation over large time periods, time-resolved fire-spread predictions are needed for active fire management.

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.

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.
