  • 融合LSTM与GRU的混合RNN模型,处理时间序列数据。
  • 模型准确复现火灾热点的年度峰值与谷值周期模式。
  • 适合环境监测、气候变化研究者参考使用。

本研究提出一种综合方法,用于建模和预测巴西亚马孙地区由AQUA-MT卫星检测到的历史活跃火点时间序列。采用结合长短期记忆网络(LSTM)与门控循环单元(GRU)的混合循环神经网络(RNN)模型,预测每日检测到的活跃火点的月累计数量。数据分析显示,火点数量具有稳定的季节性,每年的最高值与最低值在相同时间段重复出现。研究目标是验证机器学习方法能否有效捕捉这一内在季节性特征。方法包括细致的数据准备、模型配置及使用两种随机种子进行交叉验证训练,确保模型在测试集与验证集上均具有良好泛化能力。结果表明,混合的LSTM-GRU模型表现出优异的预测性能,有效捕捉复杂的时间动态并拟合观测时间序列。该研究显著推动了深度学习在环境监测中的应用,特别是在活跃火点预测方面。所提方法具备可扩展性,可应用于其他时间序列预测任务,为机器学习与自然现象预测的研究与开发开辟新路径。

原文摘要 · Abstract (English)

This study presents a comprehensive methodology for modeling and forecasting the historical time series of active fire spots detected by the AQUA\_M-T satellite in the Amazon, Brazil. The approach employs a mixed Recurrent Neural Network (RNN) model, combining Long Short-Term Memory (LSTM) and Gated Recurrent Unit (GRU) architectures to predict the monthly accumulations of daily detected active fire spots. Data analysis revealed a consistent seasonality over time, with annual maximum and minimum values tending to repeat at the same periods each year. The primary objective is to verify whether the forecasts capture this inherent seasonality through machine learning techniques. The methodology involved careful data preparation, model configuration, and training using cross-validation with two seeds, ensuring that the data generalizes well to both the test and validation sets for both seeds. The results indicate that the combined LSTM and GRU model delivers excellent forecasting performance, demonstrating its effectiveness in capturing complex temporal patterns and modeling the observed time series. This research significantly contributes to the application of deep learning techniques in environmental monitoring, specifically in forecasting active fire spots. The proposed approach highlights the potential for adaptation to other time series forecasting challenges, opening new opportunities for research and development in machine learning and prediction of natural phenomena. Keywords: Time Series Forecasting; Recurrent Neural Networks; Deep Learning.
