Evaluación de la influencia de ciertos atributos en un problema de clasificación
L. Davila Pena, I. García Jurado, B. Casas Méndez
En este trabajo se utilizan técnicas de machine learning para tratar un tema de gran relevancia en los problemas de clasificación: la evaluación de la influencia de cada uno de los atributos en la clasificación de los individuos. En concreto, se introduce una medida de dicha influencia utilizando el valor de Shapley y se proporciona una caracterización axiomática basada en las propiedades de eficiencia y contribuciones equilibradas. Además, se han diseñado algunos experimentos para validar el adecuado funcionamiento de dicha medida. Por último, la metodología introducida se aplica a una muestra de pacientes infectados por COVID-19 para estudiar la influencia de ciertos factores demográficos o de riesgo en diversos eventos de interés relacionados con la evolución de la enfermedad, como pueden ser la hospitalización, el ingreso en la UCI o el fallecimiento.
Keywords: Machine learning, clasificación, influencia de los atributos, valor de Shapley, COVID-19
