| 摘 要： | 为支持向量回归机提供了一个新的光滑函数,即运用三次样条函数和复合函数的方法,得到一种新的光滑支持向量回归机——三次样条光滑支持向量回归机(TSSSVR).对该支持向量回归机的光滑函数进行了逼近性能和收敛性的分析,并说明该光滑函数比以往的光滑函数具有更高的逼近精度和收敛速度.

| Abstract: | A new method in which the three-order spline function was used to smooth the model of support vector regression(SVR) was presented.A third-order spline smooth support vector regression(TSSSVR) was obtained.Moreover,by analyzing the function approximation and convergence capability,it is shown TSSSVR has higher precision than other previous smoothing functions. |
