| 2 | Multi-outputs Gaussian process for predicting Burkina Faso COVID-19 spread using correlations from the weather parameters显示文摘The novel coronavirus has affected all regions of the world,but each country has experienced different rates of infection.InWest Africa,in particular,infection rates remain low as compared to other parts of the world.This heterogeneity in the spread of COVID-19 raises a lot of questions that are still unanswered.However,some studies point out that people's mobility,size of gatherings,rate of testing,and weather have a great impact on the COVID-19 spread.In this work,we first evaluate the correlation between meteorological parameters and COVID-19 cases using Spearman's rank correlation.Secondly,multi-output Gaussian processes(MOGP)are used to predict the daily confirmed COVID-19 cases by exploring its relationships with meteorological parameters.The number of daily reported COVID-19 cases,as well as,weather variables collected from March 9,2020,to October 18,2021,were used in the analysis.The weather variables considered in the analysis are the mean temperature,relative humidity,wind direction,insolation,precipitation,and wind speed.The predicting model was constructed exploiting the correlation between the data of the daily confirmed COVID-19 cases and data of the weather variables.The results show that a significant correlation between the daily confirmed COVID-19 cases was found with humidity,wind direction,wind speed,and insolation.These parameters are used to construct the predictive model using the Multi-Output Gaussian process(MOGP).Different combinations of the data of meteorological parameters together with the data of daily reported COVID-19 cases were used to derive different models.We found that the best predictor is obtained using the combination of Humidity and insolation.This model is then used to predict the daily confirmed COVID-19 cases knowing the humidity and Insolation. | Souleymane Zio Bernard Lamien Sibiri Tiemounou Yoda Adaman Inoussa Tougri Mohamed Beidari Ouedraogo W.Y.S.Boris | 2022 | Infectious Disease Modelling2022，7，3： | 0 |
