Software reliability prediction based on improved PSO-SVM model

The major disadvantages of the current software reliability models were discussed.And then based on analyzing classic PSO-SVM model and the characteristics of software reliability prediction,some measures of the improved PSO-SVM model were proposed and an improved model was established.Lastly,the simulation results show that compared with classic models,the improved model has better prediction precision,better generalization ability and lower dependence on the number of sample,which is more applicable for software reliability prediction.
