Abstract
En 中文
Feature selection (FS) is an essential step for machine learning problems that can improve the performance of the classification by removing useless features from the data set. FS is an NP-hard problem, so meta-heuristic algorithms can be used to find good solutions for this problem. Horse herd Optimization Algorithm (HOA) is a new meta-heuristic approach inspired by horses 'herding behavior. In this paper, an improved version of the HOA algorithm called BHOA is proposed as a wrapper-based FS method. To convert continuous to discrete search space, S-Shaped and V-Shaped transfer functions are considered. Moreover, to control selection pressure, exploration, and exploitation capabilities, the Power Distance Sums Scaling approach is used to scale the fitness values of the population. The efficiency of the proposed method is estimated on 17 standard benchmark datasets. The implementation results prove the efficiency of the proposed method based on the V-shaped category of transfer functions compared to other transfer functions and other wrapper-based FS algorithms.
