Abstract

In recent years, ensuring food security has become a global concern, necessitating accurate forecasting of agriculture security to aid in policymaking and resource allocation. This article proposes the utilization of transformers, a powerful deep learning technique, for predicting the Agriculture Security Index ( A S I). The A S I is a comprehensive metric that evaluates the stability and resilience of agricultural systems. By harnessing the temporal dependencies and complex patterns present in historical A S I data, transformers offer a promising approach for accurate and reliable forecasting. The transformer architecture, renowned for its ability to capture long-range dependencies, is tailored to suit the A S I forecasting task. The model is trained using a combination of supervised learning and attention mechanisms to identify salient features and capture intricate relationships within the data. To evaluate the performance of the proposed method, various evaluation metrics, including mean absolute error, root mean square error, and coefficient of determination, are employed to assess the accuracy, robustness, and generalizability of the transformer-based forecasting approach. The results obtained demonstrate the efficacy of transformers in forecasting the A S I, outperforming traditional time series forecasting methods. The transformer model showcases its ability to capture both short-term fluctuations and long-term trends in the A S I, allowing policymakers and stakeholders to make informed decisions. Additionally, the study identifies key factors that significantly influence agriculture security, providing valuable insights for proactive intervention and resource allocation.

预测农业安全指数:来自变压器方法的证据
近年来,确保粮食安全已成为全球关注的问题,因此有必要对农业安全进行准确预测,以帮助决策和资源分配。本文提出利用变压器这一强大的深度学习技术来预测农业安全指数()。农业安全指数是评估农业系统稳定性和复原力的综合指标。通过利用历史数据中存在的时间依赖性和复杂模式,变压器为准确可靠的预测提供了一种前景广阔的方法。变压器架构以其捕捉长程依赖性的能力而闻名,是为适应预测任务而量身定制的。该模型采用监督学习和注意力机制相结合的方法进行训练,以识别突出特征并捕捉数据中错综复杂的关系。为了评估所提出方法的性能,采用了各种评估指标,包括平均绝对误差、均方根误差和判定系数,以评估基于变压器的预测方法的准确性、稳健性和通用性。得出的结果表明,变换器在预报 "飓风"、"暴风雪 "和 "暴雨 "方面的功效优于传统的时间序列预报方法。变压器模型展示了其捕捉 "飓风 "的短期波动和长期趋势的能力,使政策制定者和利益相关者能够做出明智的决策。此外,该研究还确定了严重影响农业安全的关键因素,为主动干预和资源分配提供了宝贵的见解。
