摘要:

由于气候变化的影响日益加剧,野火预测变得愈发关键。传统的基于CNN的野火预测模型在处理缺失的海洋数据以及解决气象数据中遥远区域间的长距离依赖关系方面存在困难。本文引入了一种创新的基于图神经网络(GNN)的全球野火预测模型。我们提出了一种混合模型,将图卷积网络(GCNs)的空间优势与长短期记忆网络(LSTM)的时间深度相结合。我们的方法独特地将全球气候和野火数据转换为图表示,解决了传统模型中固有的海洋数据位置为空以及长距离依赖等挑战。通过使用未见过的JULES-INFERNO模拟集合与现有架构进行基准测试,我们的模型展现出卓越的预测准确性。此外,我们强调模型的可解释性,通过社区发现揭示潜在的野火相关集群,并通过Integrated Gradient分析阐明特征重要性。我们的研究结果不仅推进了野火预测的方法学领域,还强调了模型透明度的重要性,为野火管理利益相关者提供了宝贵见解。

英文摘要:

Wildfire prediction has become increasingly crucial due to the escalating impacts of climate change. Traditional CNN-based wildfire prediction models struggle with handling missing oceanic data and addressing the long-range dependencies across distant regions in meteorological data. In this paper, we introduce an innovative Graph Neural Network (GNN)-based model for global wildfire prediction. We propose a hybrid model that combines the spatial prowess of Graph Convolutional Networks (GCNs) with the temporal depth of Long Short-Term Memory (LSTM) networks. Our approach uniquely transforms global climate and wildfire data into a graph representation, addressing challenges such as null oceanic data locations and long-range dependencies inherent in traditional models. Benchmarking against established architectures using an unseen ensemble of JULES-INFERNO simulations, our model demonstrates superior predictive accuracy. Furthermore, we emphasise the model's explainability, unveiling potential wildfire correlation clusters through community detection and elucidating feature importance via Integrated Gradient analysis. Our findings not only advance the methodological domain of wildfire prediction but also underscore the importance of model transparency, offering valuable insights for stakeholders in wildfire management.
