Least square vector machines had the quickly solving speed and the excellent characteristics to describe the little samples
nonlinear and high dimensions problem. But the regression accuracy and generalization performance of this method depend on a proper setting of its parameters. So
an optimal selection approach of LSSVM was presented based on particle swarm optimization (PSO) algorithm. Then
the prediction on the thickness of the loosen zone around roadway is made by PSO-LSSVM model
and the results show that this model has the characteristic of quickly convergence speed and highly calculating precision .So
