使用最佳运输连接COVID-19动态和人类移动性的聚类模式

Clustering patterns connecting COVID-19 dynamics and Human mobility using optimal transport

摘要:

社交距离及待在家中是已知可有效遏止COVID-19等大流行病在特定人群中传播的少数措施之一。这些措施之间的依赖关系及其对疾病发病率的影响可能因人口而异。我们描述了一个新的计算框架,用于测量和比较美国150多个发病率相对较高的城市中人员流动与新冠肺炎病例之间的时间关系。我们使用了一个新的应用程序的最优运输计算之间的距离的规范化模式诱导的双变量时间序列为每对城市。因此,我们确定了10个具有相似时间依赖性的城市集群,并计算了Wasserstein重心来描述每个集群的整体动态模式。最后,我们使用特定城市的社会经济协变量来分析每个聚类的组成。

英文摘要:

Social distancing and stay-at-home are among the few measures that are known to be effective in checking the spread of a pandemic such as COVID-19 in a given population. The patterns of dependency between such measures and their effects on disease incidence may vary dynamically and across different populations. We described a new computational framework to measure and compare the temporal relationships between human mobility and new cases of COVID-19 across more than 150 cities of the United States with relatively high incidence of the disease. We used a novel application of Optimal Transport for computing the distance between the normalized patterns induced by bivariate time series for each pair of cities. Thus, we identified 10 clusters of cities with similar temporal dependencies, and computed the Wasserstein barycenter to describe the overall dynamic pattern for each cluster. Finally, we used city-specific socioeconomic covariates to analyze the composition of each cluster.
