Unplanned fire is a major control on the nature of terrestrial ecosystems and causes substantial losses of life and property. Given the substantial influence of climatic conditions on fire incidence, climate change is expected to substantially change fire regimes in many parts of the world. We wished to determine whether it was possible to develop a deep neural network process for accurately estimating continental fire incidence from publicly available climate data. We show that deep recurrent Elman neural network was the best performed out of ten artificial neural networks (ANN) based cognitive imaging systems for determining the relationship between fire incidence and climate. In a decennium data experiment using this ANN we show that it is possible to develop highly accurate estimations of fire incidence from monthly climatic data surfaces. Our estimations for the continent of Australia had over 90% global accuracy and a very low level of false negatives. The technique is thus appropriate for use in estimating the spatial consequences of climate scenarios on the monthly incidence of wildfire at the landscape scale.
意外火灾是陆地生态系统性质的主要控制因素,会导致大量生命和财产损失。鉴于气候条件对火灾发生率有重大影响,预计气候变化将在世界许多地区大幅改变火灾状况。我们希望确定是否有可能开发一种深度神经网络程序,以便根据公开可用的气候数据准确估算大陆火灾发生率。我们表明,在基于十个用于确定火灾发生率与气候之间关系的人工神经网络(ANN)的认知成像系统中,深度递归埃尔曼神经网络表现最佳。在使用此人工神经网络的十年数据实验中,我们表明可以根据月度气候数据表面高度准确地估算火灾发生率。我们对澳大利亚大陆的估算全球准确率超过90%,假阴性水平非常低。因此,该技术适用于在景观尺度上估算气候情景对野火月度发生率的空间影响。
