Multi-objective feature selection using hybridization of a genetic algorithm and direct multisearch for key quality characteristic selection

An-Da Li, Bing Xue, Mengjie Zhang

Abstract: Highlights•Three candidate bi-objective key quality characteristic selection models are proposed.•A new hybrid method of a GA and direct multisearch is proposed for optimization.•The model with geometric mean measure performs better than the other two models.•The proposed method effectively addresses the production data imbalance problem.•The optimization approach shows better search performance than benchmark methods.
