Support vector machines (SVMs) have become one of the most useful mathematical programming approaches for supervised classification.The classical soft-margin SVM model minimizes an objective function given by the inverse of the margin between the supporting hyperplanesand the sum of the deviations of misclassified objects penalized by a parameter. In this talk, we propose an SVM model where weights are assigned to the sorted values of slack variables associated with the deviations. Thus, we include the ordered weighted average operator in the softmargin SVM. Unlike other approaches, this is a one-step method where the classical model is adequately modified.
