Semi-supervised learning using tag vector machine is a relatively new method of data classification and label-free. Semi-supervised support vector machines model the objective function is not smooth and fast optimization algorithm to solve the model cannot be applied. This paper presents a general three-moment method 3 times differentiable at the origin of construct quintic spline functions, construction of hinge can be used to approximate symmetry loss functions, the approximate accuracy estimation of and quintic spline functions. And on top of this, deduced five and a half times b-spline smoothing support vector machines for non-smooth a-smoothing model analyses the convergence. Broyden-Fletcher-Goldfarb-Shanno (storage) algorithm can be used in new models. Experimental results show that the new model has a better performance.
