| Abstract: | The support vector machines （SVM） is a kind of novel statistics learning method.In the case of small samples,SVM has a higher classification capability.In this paper,SVM with composite kernels will be adopted to optimize the parameters of SVM with the particle swarm optimization （PSO） and to carry out the experiments on the UCI database.Compared with the single kernel SVM,the composite kernels can improve precision of classification and get a better classification performance.Finally,we use SVM with composite kernels in the fault diagnosis of wind power gearbox and have a good result. |
