Abstract

In the present article a hyperparameter optimization of a vectorial-support regression machine via adaptation of metaheuristics of a particle swarm is proposed. This method will be used so that a forecasting of the time series of the total amount of positive accumulated cases of COVID-19 in Bogotá, Colombia. In order to validate the performance of the method, a comparison with a regression vectorial-support machine whose hyperparameters have not been optimized will be made, being the metrics those of performance measurement like mean square error, mean absolute error, and determination coefficient. The proposed method finds itself at a greater level of performance when the mean square error value is that of 0,000045, the determination coefficient corresponds with the value of 0,998884 and the p-value of 0,0015, for the nonparametric Wilcoxon test. Finally, applicability of these sorts of methods for forecasting of cases-behavior amidst epidemics is discussed.
