Neural Bayes Estimators for Irregular Spatial Data using Graph Neural Networks

2 code implementations4 Oct 2023 Matthew Sainsbury-Dale, Jordan Richards, Andrew Zammit-Mangion, Raphaël Huser

Neural Bayes estimators are neural networks that approximate Bayes estimators in a fast and likelihood-free manner.

Deep graphical regression for jointly moderate and extreme Australian wildfires

no code implementations28 Aug 2023 Daniela Cisneros, Jordan Richards, Ashok Dahal, Luigi Lombardo, Raphaël Huser

Recent wildfires in Australia have led to considerable economic loss and property destruction, and there is increasing concern that climate change may exacerbate their intensity, duration, and frequency.

Neural Bayes estimators for censored inference with peaks-over-threshold models

2 code implementations27 Jun 2023 Jordan Richards, Matthew Sainsbury-Dale, Andrew Zammit-Mangion, Raphaël Huser

Making inference with spatial extremal dependence models can be computationally burdensome since they involve intractable and/or censored likelihoods.

Insights into the drivers and spatio-temporal trends of extreme Mediterranean wildfires with statistical deep-learning

1 code implementation4 Dec 2022 Jordan Richards, Raphaël Huser, Emanuele Bevacqua, Jakob Zscheischler

Our results highlight that whilst VPD, air temperature, and drought significantly affect wildfire occurrence, only VPD affects wildfire spread.

Regression modelling of spatiotemporal extreme U.S. wildfires via partially-interpretable neural networks

1 code implementation16 Aug 2022 Jordan Richards, Raphaël Huser

In this paper, we propose a new methodological framework for performing extreme quantile regression using artificial neutral networks, which are able to capture complex non-linear relationships and scale well to high-dimensional data.

Spatial deformation for non-stationary extremal dependence

1 code implementation18 Jan 2021 Jordan Richards, Jennifer L. Wadsworth

Modelling the extremal dependence structure of spatial data is considerably easier if that structure is stationary.
