Algorithms for data classification are normally at their high performance when the dataset has good balance in which the number of data instances in each class is approximately equal.But when the dataset is imbalanced, the classification model tends to bias toward the majority class.The goal of imbalanced data classification is how to improve the performance of a model to better recognize data from minority class, especially when minority is more interesting than the majority data.In this research, we propose technique for balancing data with hybrid resampling techniques and then perform parameter optimization with restarting genetic algorithm.The optimized parameters are for support vector machine to induce efficient model for recognizing data in minority class, whereas maintaining overall accuracy.The experimental results show that the proposed technique has high performance than others.
