【Abstract】 Using a class of new smoothing functions, the problem of smoothing support vector machines was studied. A new 3rd-order polynomial smooth support vector machine (3SSVM) model was proposed, and its 3rd-order smoothness and global convergence was proved. Numerical experiments were carried out to evaluate the 3SSVM by using Newton-Armijo algorithm. The results show that the 3SSVM model is better than the PSSVM model and the SSVM model, providing better theoretical support for applications of smooth support vector machines.更多还原
