“…The filter mechanism is more about the relation or correlation between the features without considering the class label, whereas the wrapper feature selection depends entirely on the class label to select the most important features. The wrapper technique can be employed using metaheuristic algorithms, such as Genetic Algorithm (GA) ( Al-Qudah et al, 2020a ; Al-Qudah et al, 2020b ), Particle swarm optimization(PSO) ( Rostami et al, 2020 ), Multi-Verse Optimizer (MVO) ( Sadiq et al, 2019 ), Salp Swarm Algorithm (SSA) ( Ala’M et al, 2020 ), Whale Optimization Algorithm (WOA) ( Ala’M et al, 2018 ) and Competitive Swarm Optimizer (CSO) ( Ala’M et al, 2021 ). To accomplish the feature selection task, Petkovic et al, (2014) and Petkovic et al (2016) used GINI index whereas Naseer, Zhang & Zhu (2020a) used information gain.…”
