GEO-Bench: Toward Foundation Models for Earth Monitoring

1 code implementation NeurIPS 2023 Alexandre Lacoste, Nils Lehmann, Pau Rodriguez, Evan David Sherwin, Hannah Kerner, Björn Lütjens, Jeremy Andrew Irvin, David Dao, Hamed Alemohammad, Alexandre Drouin, Mehmet Gunturkun, Gabriel Huang, David Vazquez, Dava Newman, Yoshua Bengio, Stefano Ermon, Xiao Xiang Zhu

Recent progress in self-supervision has shown that pre-training large neural networks on vast amounts of unsupervised data can lead to substantial increases in generalization to downstream tasks.

Multiscale Neural Operator: Learning Fast and Grid-independent PDE Solvers

no code implementations23 Jul 2022 Björn Lütjens, Catherine H. Crawford, Campbell D Watson, Christopher Hill, Dava Newman

Numerical simulations in climate, chemistry, or astrophysics are computationally too expensive for uncertainty quantification or parameter-exploration at high-resolution.

Spectral PINNs: Fast Uncertainty Propagation with Physics-Informed Neural Networks

no code implementations NeurIPS Workshop DLDE 2021 Björn Lütjens, Catherine H Crawford, Mark Veillette, Dava Newman

We aim to quickly quantify the impact of uncertain parameters onto the solution of a PDE - that is - we want to perform fast uncertainty propagation.

WiSoSuper: Benchmarking Super-Resolution Methods on Wind and Solar Data

no code implementations17 Sep 2021 Rupa Kurinchi-Vendhan, Björn Lütjens, Ritwik Gupta, Lucien Werner, Dava Newman

We provide a thorough and extensible benchmark of leading deep learning-based super-resolution techniques, including the enhanced super-resolution generative adversarial network (ESRGAN) and an enhanced deep super-resolution (EDSR) network, on wind and solar data.

PCE-PINNs: Physics-Informed Neural Networks for Uncertainty Propagation in Ocean Modeling

no code implementations5 May 2021 Björn Lütjens, Catherine H. Crawford, Mark Veillette, Dava Newman

Climate models project an uncertainty range of possible warming scenarios from 1. 5 to 5 degree Celsius global temperature increase until 2100, according to the CMIP6 model ensemble.
