Abstract
On the basis of research on multi-classification algorithm of SVM
aiming at problem of inseparable area appeared in one-versus-one multi-classification algorithm
the secondary subdivision method based on the one-versus-one multi-classification algorithm based on SVM is proposed.And this method is applied to classify the small samples data of the spring stress in the simulation experiment.Compared with the simulation results of original method
the new method improves correct rate of classification which it costs some extra time.Aiming at problems the improved method possibly has
the feasibility is verified through ten simulation experiments.At the same time
it provides a new concept in classification field of the small samples.
