Abstract

En 中文
Feature selection is a fundamental step in machine learning, serving to reduce dataset redundancy, accelerate training speed, and improve model quality. This is particularly crucial in high-dimensional datasets, where the excess of features presents challenges for pattern recognition and data analysis. Recent methods proposed for high-dimensional data are often tailored for specific domains, leaving a lack of consensus on a universally recommended solution for general use cases. This paper proposes a hybrid feature selection approach using a multi-objective genetic algorithm to enhance classification performance and reduce dimensionality across diverse classification tasks. The proposed approach narrows the search space of possible relevant features by exploring the combined outputs of classical feature selection methods through novel genetic algorithm operators. This enables the evolution of combined solutions potentially not explored by the original methods, generating optimized feature sets in a process that adapts to different data conditions. Experimental results demonstrate the effectiveness of the proposed method in high-dimensional use cases, offering improved classification performance with reduced feature sets. In summary, our hybrid method offers a promising solution for addressing the challenges of high-dimensional datasets by enhancing classification performance in varying domains and data conditions.
