In order to investigate the property of neural network generalization more roundly,a mode for the testing data is proposed and the generalization capability of the support vector machine(SVM) network of this work and the probabilistic neural network(PNN) of a previous work are compared with the data produced by the mode.The simulation results show that the SVM network provides better generalization capability than that of the PNN in terms of generalization for either laboratory data or changes in experimental conditions.
