Abstract

IntroductionFrom public health perspectives of COVID-19 pandemic, accurate estimates of infection severity of individuals are extremely valuable for the informed decision-making and targeted response to an emerging pandemic. This paper presents machine learning based prognostic model for providing early warning to the individuals for COVID-19 infection using the healthcare dataset. In the present work, a prognostic model using random forest classifier and support vector regression is developed for predicting the infection susceptibility probability (ISP) score of COVID-19, and it is applied on an open healthcare dataset containing 27 field values. The typical fields of the healthcare dataset include basic personal details such as age, gender, number of children in the household, and marital status along with medical data like coma score, pulmonary score, blood glucose level, HDL cholesterol, etc. An effective preprocessing method is carried out for handling the numerical and categorical values (non-numerical) and missing data in the healthcare dataset. The correlation between the variables in the healthcare data is analyzed using the correlation coefficient, and heat map with a color code is used to identify the influencing factors on the infection susceptibility probability (ISP) score of COVID-19. Based on the accuracy, precision, sensitivity, and F-scores, it is noted that the random forest classifier provides an improved classification performance as compared to support vector regression for the given healthcare dataset.
