新型冠状病毒SARS-CoV-2引起的新型冠状病毒COVID-19在全球蔓延,对人类构成重大威胁。随着COVID-19疫情的持续发展,预测局部疾病的严重程度对于提前分配资源至关重要。本文提出了一种名为COUptage(COUnty aggRegation mixup AugmEntation)的方法,利用现代深度学习技术,为美国每个县的COVID-19相关死亡人数生成两周前的短期预测。具体来说,我们的方法采用了自然语言处理中的自注意模型,称为Transformer模型,以捕获时间序列中的短期和长期依赖关系,同时享受计算效率。我们的模型仅利用与COVID-19相关的确诊病例、死亡人数、社区流动趋势和人口统计信息的公开信息,并可将相应的县级预测汇总生成州级预测。我们的数值实验表明,我们的模型达到了最先进的性能之间的公开可用的基准模型。
The global spread of COVID-19, the disease caused by the novel coronavirus SARS-CoV-2, has casted a significant threat to mankind. As the COVID-19 situation continues to evolve, predicting localized disease severity is crucial for advanced resource allocation. This paper proposes a method named COURAGE (COUnty aggRegation mixup AuGmEntation) to generate a short-term prediction of 2-week-ahead COVID-19 related deaths for each county in the United States, leveraging modern deep learning techniques. Specifically, our method adopts a self-attention model from Natural Language Processing, known as the transformer model, to capture both short-term and long-term dependencies within the time series while enjoying computational efficiency. Our model solely utilizes publicly available information for COVID-19 related confirmed cases, deaths, community mobility trends and demographic information, and can produce state-level predictions as an aggregation of the corresponding county-level predictions. Our numerical experiments demonstrate that our model achieves the state-of-the-art performance among the publicly available benchmark models.
