Abstract In this paper, a resampling ensemble algorithm is developed focused on the classification problems for imbalanced datasets. In this method, the small classes are oversampled and large classes are undersampled. The resampling scale is determined by the ratio of the minimum number of class and maximum number of class. Oversampling for “small” classes is done by MWMOTE technique and undersampling for “large” classes is performed according to SSO technique. Our aim is to reduce the time complexity as well as the enhancement of accuracy rate of classification result.
