Support vector machine has a better classification and prediction performance on balance data classification, but has a poor performance for imbalance data. In this paper, the reason of the poor results which were produced by imbalance data is explained. And a new approach is proposed to solve the imbalance data classification. By this method the imbalance data problem is converted to several i...

Class imbalance exists in many data domains, posing numerous challenges to the research community. Medical datasets, most cases are predominantly imbalanced nature. Through tackling multi-class issues, researchers preferred conventional method of decomposing it into binary classes for a more convenient solution. This is not applicable solving sensitive and crucial such as medical data. Classify...
