Ensemble feature selection using bi-objective genetic algorithm

作者:

Highlights:

• An ensemble parallel processing bi-objective genetic algorithm based feature selection method is proposed.

• Rough set theory and Mutual information gain are used to select informative data removing the vague one.

• Parallel processing in genetic algorithm reduces time complexity.

• The method is compared with the existing state-of-the-art methods using suitable datasets.

• Classification accuracy and statistical measures outperforms that of other state-of-the-art methods.
