Abstract: In this study, we have proposed hybridization of binary grey wolf Optimization and particle swarm optimization (BGWOPSO) method and we compared this hybrid optimization method with Particle Swarm Optimization (PSO) and Binary Grey Wolf Optimization (BGWO). We have used five significantly different classifier such as K-nearest Neighbor (KNN), Support Vector Machine (SVM), Artificial Neural Network (ANN), Logistic Regression (LR), Random Forest (RF). Furthermore, we have used ratio comparison validation for the 10-folds cross-validation method for feature selection methods. Data sets such as Leukemia, Breast Cancer, and Liver Cancer are used to apply the combinations and measure accuracy as well as the area under ROC. Moreover, the results show that Hybrid optimization method (BWOPSO), significantly outperformed the both binary grey wolf optimization (BGWO) and particle swarm optimization (PSO) method, when using several performance measures including accuracy, selecting the best optimal features. Secondly, combinations of classifier and feature pre-processing method significantly improve the accuracy. Lastly, the AUC value is been displayed in this study.
