Abstract The Time Adaptive Support Vector Machine (TA-SVM) algorithm exhibits good performance for nonstaionary datasets. However, insufficient information from adjacent subclassifier may lower the reliability of the obtained classification model and weakens its usefulness. A novel classifier named Evolving Support Vector Machines (ESVM) is proposed in this study by defining the relationship decaying function of the subclassifier serial. The evolving relationship between all the subclassifiers are considered in ESVM, thus a more smoothing subclassifier serial can be obtained by constraining the weighted variance between all subclassifiers, conforming with the characteristic of drifting concept hidden in the data. The effectiveness of the proposed ESVM is also experimentally verified.
