新型野火模型结合了随机森林和元胞自动机

研究人员开发了一个新颖的三阶段大规模野火蔓延建模框架,该框架整合了随机森林(RF)模型和元胞自动机(CA)。该框架首先使用在2021年加拿大火灾季训练的RF模型来估算每日像素级别的火灾发生概率。随后使用分位数梯度提升模型来提供可选的蔓延速率先验,并使用一个RF驱动的CA,将RF概率层与5公里网格上的邻域驱动蔓延相结合。在后续数据集上,RF模型表现出强劲的性能,AUC值在0.725到0.795之间,并且在2023年的模拟中,结合了RF的CA与仅使用CA的基线相比,空间重叠度显著提高。 AI

影响 这种新的建模框架通过整合机器学习概率和局部蔓延动力学,有可能提高大规模野火模拟的准确性。
