A Machine Learning Outlook: Post-processing of Global Medium-range Forecasts

no code implementations28 Mar 2023 Shreya Agrawal, Rob Carver, Cenk Gazen, Eric Maddy, Vladimir Krasnopolsky, Carla Bromberg, Zack Ontiveros, Tyler Russell, Jason Hickey, Sid Boukabara

Post-processing typically takes the outputs of a Numerical Weather Prediction (NWP) model and applies linear statistical techniques to produce improve localized forecasts, by including additional observations, or determining systematic errors at a finer scale.

Global Extreme Heat Forecasting Using Neural Weather Models

no code implementations23 May 2022 Ignacio Lopez-Gomez, Amy McGovern, Shreya Agrawal, Jason Hickey

We find that training models to minimize custom losses tailored to emphasize extremes leads to significant skill improvements in the heat wave prediction task, compared to NWMs trained on the mean squared error loss.

Skillful Twelve Hour Precipitation Forecasts using Large Context Neural Networks

2 code implementations14 Nov 2021 Lasse Espeholt, Shreya Agrawal, Casper Sønderby, Manoj Kumar, Jonathan Heek, Carla Bromberg, Cenk Gazen, Jason Hickey, Aaron Bell, Nal Kalchbrenner

An emerging class of weather models based on neural networks represents a paradigm shift in weather forecasting: the models learn the required transformations from data instead of relying on hand-coded physics and are computationally efficient.

Freeform Diffractive Metagrating Design Based on Generative Adversarial Networks

no code implementations29 Nov 2018 Jiaqi Jiang, David Sell, Stephan Hoyer, Jason Hickey, Jianji Yang, Jonathan A. Fan

A key challenge in metasurface design is the development of algorithms that can effectively and efficiently produce high performance devices.

Data-driven discretization: a method for systematic coarse graining of partial differential equations

3 code implementations15 Aug 2018 Yohai Bar-Sinai, Stephan Hoyer, Jason Hickey, Michael P. Brenner

Many problems in theoretical physics are centered on representing the behavior of a physical theory at long wave lengths and slow frequencies by integrating out degrees of freedom which change rapidly in time and space.
