RESUMO

Feature selection is becoming a relevant problem within the field of machine learning. The feature selection problem focuses on the selection of the small, necessary, and sufficient subset of features that represent the general set of features, eliminating redundant and irrelevant information. Given the importance of the topic, in recent years there has been a boom in the study of the problem, generating a large number of related investigations. Given this, this work analyzes 161 articles published between 2019 and 2023 (20 April 2023), emphasizing the formulation of the problem and performance measures, and proposing classifications for the objective functions and evaluation metrics. Furthermore, an in-depth description and analysis of metaheuristics, benchmark datasets, and practical real-world applications are presented. Finally, in light of recent advances, this review paper provides future research opportunities.

RESUMO

La cantidad de personas que ascienden a la tercera edad aumentó en 700 millones en la década del 90, a nivel mundial. Para el año 2025 se estima que existirán cerca de 2 mil millones de ancianos. El cuidado de su salud reviste vital importancia para todas las sociedades; por ello, en el presente trabajo se propone una herramienta matemático computacional para medir la ejercitación de la atención y la percepción en el ambiente diario del adulto mayor. Ambas funciones poseen una estrecha relación con la capacidad psicológica de la memoria; además, se considera que su afectación puede provocar pérdida de validismo, dependencia y discapacidad, una vez que se ha iniciado el deterioro cognitivo. La propuesta es aplicada en la ciudad de Pinar del Río, Cuba a través de test experimentales y diferentes tipos de análisis mediante medios de cómputo en una muestra de personas de la tercera edad, con una capacidad moderadamente razonable(AU)


The number of old persons increased in 700 millions in the 90's at world level. This number will increase to nearly 2 thousand more million in 2025. The carefulness of their healthy becomes an important issue for all societies; that is why, in this research, it is presented a computational tool to measure the assistance and the perception in the daily environment of the elderly people. Both functions have a close relationship with the psychological capacity of the memory; moreover, it is considered that their damage can provoke loss of skills, dependence and disabilities, once the cognitive deterioration has begun. The proposal is applied in the pinar del rÝo, cuba, through experimental tests and different types of analysis by means of computational in a sample of elderly people with a moderately reasonable capacity(AU)
