AI总结:

本文系统综述了神经网络在登革热预测中的应用,指出其在预测性能上的竞争力及未来研究方向。

摘要:

背景:早期的登革热预测是疾病防控的重要工具。神经网络是强大的预测模型,已在公共卫生的许多领域做出了贡献。在本研究中,我们回顾了神经网络在登革热预测文献中的应用,旨在为未来的工作提供模型设计的指导。\n方法:根据PRISMA指南,我们系统地搜索了使用神经网络预测人类群体中登革热的研究。我们总结了神经网络和比较模型的相对性能、架构和超参数、输入特征的选择、地理分布以及模型透明性。\n结果:纳入了62篇论文。大多数研究采用了浅层前馈神经网络,使用历史登革热发病率和气候变量。预测时间跨度差异很大,模型选择和评估方法也各不相同。基于神经网络的优势,大多数研究使用了城市层面或其细分地区的精细观测数据,同时通常采用每周数据。神经网络相对于比较模型,如基于树的监督模型,在不同研究环境中表现各异,我们发现63%的所有研究至少包含一个此类模型作为基线,而在这些情况下,大约一半的研究报告神经网络表现最佳。\n结论:这些研究表明,神经网络可以为登革热提供具有竞争力的预测,并且可以可靠地包含在未来的登革热预测努力的候选模型集合中。使用深度网络相对未被探索,但提供了进一步研究的有前途的途径,此外,使用更广泛的输入特征和在数据生成机制结构变化的情况下进行预测也值得进一步研究。

英文摘要:

Background: Early forecasts of dengue are an important tool for disease mitigation. Neural networks are powerful predictive models that have made contributions to many areas of public health. In this study, we reviewed the application of neural networks in the dengue forecasting literature, with the objective of informing model design for future work. Methods: Following PRISMA guidelines, we conducted a systematic search of studies that use neural networks to forecast dengue in human populations. We summarized the relative performance of neural networks and comparator models, architectures and hyper-parameters, choices of input features, geographic spread, and model transparency. Results: Sixty two papers were included. Most studies implemented shallow feed-forward neural networks, using historical dengue incidence and climate variables. Prediction horizons varied greatly, as did the model selection and evaluation approach. Building on the strengths of neural networks, most studies used granular observations at the city level, or on its subdivisions, while also commonly employing weekly data. Performance of neural networks relative to comparators, such as tree-based supervised models, varied across study contexts, and we found that 63% of all studies do include at least one such model as a baseline, and in those cases about half of the studies report neural networks as the best performing model. Conclusions: The studies suggest that neural networks can provide competitive forecasts for dengue, and can reliably be included in the set of candidate models for future dengue prediction efforts. The use of deep networks is relatively unexplored but offers promising avenues for further research, as does the use of a broader set of input features and prediction in light of structural changes in the data generation mechanism.
