MotifDisco: Motif Causal Discovery For Time Series Motifs

no code implementations23 Sep 2024 Josephine Lamp, Mark Derdzinski, Christopher Hannemann, Sam Hatfield, Joost van der Linden

Therefore, in this paper we develop MotifDisco (motif disco-very of causality), a novel causal discovery framework to learn causal relations amongst motifs from time series traces.

2 code implementations13 Nov 2023 Dmitrii Kochkov, Janni Yuval, Ian Langmore, Peter Norgaard, Jamie Smith, Griffin Mooers, Milan Klöwer, James Lottes, Stephan Rasp, Peter Düben, Sam Hatfield, Peter Battaglia, Alvaro Sanchez-Gonzalez, Matthew Willson, Michael P. Brenner, Stephan Hoyer

Here we present the first GCM that combines a differentiable solver for atmospheric dynamics with ML components, and show that it can generate forecasts of deterministic weather, ensemble weather and climate on par with the best ML and physics-based methods.

Machine learning emulation of gravity wave drag in numerical weather forecasting

no code implementations20 Jan 2021 Matthew Chantry, Sam Hatfield, Peter Duben, Inna Polichtchouk, Tim Palmer

By training on an increased complexity version of the existing parameterisation scheme we build emulators that produce more accurate forecasts.
