Combining Linear Regressions to Determine the Future of the Covid in Mexico from the News

ABSTRACT

This paper presents an approach to determine the Semaphore Covid in Mexico from the news to participate in the Rest-Mex 2022 evaluation forum. The purpose of the task is to determine the covid semaphore color (red, orange, yellow, and green) in different time spaces. The proposed approach consists of two main steps. First, to generate a list of topics of the news, and second, to implement several linear regressions methods in order to these results serve to feed a deep neural network. For the first step, the LDA algorithm was implemented, and for the second, well-known methods such as Lasso, Ridge, Lars, among others, were utilized. With this approach, a weighted average of 0.48 was obtained, which is considerably higher than the baseline proposed by the organizers, which is 0.12. The best result to classify the semaphore was two weeks in the future with 0.56 of F-measure. © 2022 Copyright for this paper by its authors.
