摘要: The purpose of this paper is to propose a new hybrid metaheuristic to solve the problem of feature selection. Feature selection problem is the process of finding the most relevant subset based on some criteria. A hybrid metaheuristic is a new trend in the development of optimization algorithms. In this paper, two different hybrid models are designed based on spotted hyena optimization (SHO) for feature selection problem. The SHO algorithm can find the optimal or nearly optimal feature subset in the feature space to minimize the given fitness function. In the first model, the simulated annealing algorithm (SA) is embedded in the SHO algorithm (called SHOSA-1) to enhance the optimal solution found by the SHO algorithm after each iteration. In the second model, SA enhances the final solution obtained by the SHO algorithm (called SHOSA-2). The performance of these methods is evaluated in 20 datasets in the UCI repository. The experiments show that SHOSA-1 performs better than the native algorithm and SHOSA-2. And then, SHOSA-1 is compared with six state-of-the-art optimization algorithms. The experimental results confirm that SHOSA-1 improves the classification accuracy and reduces the number of selected features compared with other wrapper-based optimization algorithms. That proves the excellent performance of SHOSA-1 in spatial search and feature attribute selection.

研究概述 实验方案

To propose a new hybrid metaheuristic algorithm combining spotted hyena optimization (SHO) and simulated annealing (SA) for solving the feature selection problem, aiming to improve classification accuracy and reduce the number of selected features.

The SHOSA-1 algorithm significantly improves classification accuracy and reduces the number of selected features compared to other wrapper-based optimization algorithms. It demonstrates excellent performance in spatial search and feature attribute selection, making it a promising approach for feature selection problems.

SHOSA-1 is not recommended for large datasets due to its long running time. The algorithm's performance on very high-dimensional data needs further investigation.
