In view of the problem that the existing attribute effect control method can not effectively control the attribute effect in the nonlinear regression model, an equal mean-support vector regression(EM-SVR) based on the principles of the margin maximization and the structural risk minimization is proposed by using the constraint condition of equal mean, which has the good generalization ability and the characteristic of nonlinear regression. At the same time, the good performance of equal mean-least square(EM-LS) is also inherited. Finally, the experiment results show the effectiveness of the proposed method.
