Abstract

One of the main problems that countries are currently having is being able to measure the impact of the pandemic in other areas of society (for example, economic or social). In that sense, being able to combine variables about the behavior of COVID-19 with other variables in the environment, to build models about its impact, which help the decision-making of national authorities, is a current challenge. In this sense, this work proposes an approach that allows monitoring the socioeconomic behavior of the regions/departments of a country (in this case, Colombia) due to the effect of COVID-19. To do this, an approach is proposed in which the behavior of the infected is initially predicted, and together with other context variables (climate, economics and socials) determines the current socioeconomic situation of a region. This classification of a region, with the pattern that characterizes it, is a fundamental input for those who make decisions. Thus, this work presents an approach based on machine learning techniques to identify regions with similar socioeconomic behaviors due to COVID-19, so they should eventually have similar public policies. The proposed hybrid model initially consists of a time series prediction model of infected, to which are added several context variables (climate, socioeconomic, incidence of COVID-19 at the level of deaths, suspects, etc.) in an unsupervised learning model, to determine the socioeconomic impact in the regions. Particularly, the unsupervised model groups similar regions together, and the pattern of each group describes the socioeconomic similarities between them, to help decision-makers in the process of defining policies to be implemented in the regions. The experiments showed the ability of the hybrid model to follow the evolution of the regions after 4 weeks. The quality metrics for the predictive model were around the values of 0.35 for MAPE and 0.68 for , and in the case of the clustering model were around the values of 0.3 for the Silhouette index and 0.6 for the Davies-Boulding index. The hybrid model allowed determining things like some regions that initially belonged to a group with a very low incidence of positive cases and very unfavorable socioeconomic conditions, became part of groups with moderately high incidences. Our preliminary results are very satisfactory since they allow studying the evolution of the socioeconomic impact in each region/department.

摘要

各国当前面临的主要问题之一是能否衡量疫情对社会其他领域(如经济或社会领域)的影响。从这个意义上说,能够将有关新冠疫情行为的变量与环境中的其他变量相结合,以构建其影响模型,从而帮助国家当局进行决策,是当前的一项挑战。从这个角度来看,这项工作提出了一种方法,用于监测一个国家(在本文中为哥伦比亚)各地区/部门因新冠疫情影响而产生的社会经济行为。为此,提出了一种方法,即首先预测感染者的行为,并结合其他背景变量(气候、经济和社会变量)来确定一个地区当前的社会经济状况。一个地区的这种分类及其特征模式,是决策者的重要依据。因此,这项工作提出了一种基于机器学习技术的方法,以识别因新冠疫情而具有相似社会经济行为的地区,这样它们最终应该会有相似的公共政策。所提出的混合模型最初由一个感染者时间序列预测模型组成,在一个无监督学习模型中加入了几个背景变量(气候、社会经济、新冠疫情在死亡、疑似病例等层面的发病率),以确定各地区的社会经济影响。特别是,无监督模型将相似的地区归为一组,每个组的模式描述了它们之间的社会经济相似性,以帮助决策者在确定各地区要实施的政策过程中提供参考。实验表明,混合模型能够跟踪各地区四周后的发展情况。预测模型的质量指标中,平均绝对百分比误差(MAPE)约为0.35, 约为0.68;聚类模型的质量指标中,轮廓系数约为0.3,戴维斯 - 布尔丁指数约为0.6。混合模型能够确定一些情况,比如一些最初属于阳性病例发生率很低且社会经济条件非常不利的组的地区,后来成为了发生率中等偏高的组的一部分。我们的初步结果非常令人满意,因为它们能够研究每个地区/部门社会经济影响的发展情况。
