A Neural Emulator for Uncertainty Estimation of Fire Propagation

no code implementations10 May 2023 Andrew Bolt, Conrad Sanderson, Joel Janek Dabrowski, Carolyn Huston, Petra Kuhnert

When compared to a related neural model (emulator) which was employed to generate probability maps via ensembles of emulated fires, the proposed approach produces competitive Jaccard similarity scores while being approximately an order of magnitude faster.

Bayesian Physics Informed Neural Networks for Data Assimilation and Spatio-Temporal Modelling of Wildfires

1 code implementation2 Dec 2022 Joel Janek Dabrowski, Daniel Edward Pagendam, James Hilton, Conrad Sanderson, Daniel MacKinlay, Carolyn Huston, Andrew Bolt, Petra Kuhnert

We show that popular optimisation cost functions used in the literature can result in PINNs that fail to maintain temporal continuity in modelled fire-fronts when there are extreme changes in exogenous forcing variables such as wind direction.

A Spatio-Temporal Neural Network Forecasting Approach for Emulation of Firefront Models

no code implementations17 Jun 2022 Andrew Bolt, Carolyn Huston, Petra Kuhnert, Joel Janek Dabrowski, James Hilton, Conrad Sanderson

We propose a dedicated spatio-temporal neural network based framework for model emulation, able to capture the complex behaviour of fire spread models.

An Emulation Framework for Fire Front Spread

no code implementations23 Mar 2022 Andrew Bolt, Joel Janek Dabrowski, Carolyn Huston, Petra Kuhnert

Empirical observations of bushfire spread can be used to estimate fire response under certain conditions.
