The Technical Research of the Characteristic Abstraction Based on KPCA Intrusion Detection

ion to KPCA intrusion detection system,and utilize KDDCUP99 data to draw the artificial experiment based on the characteristic abstraction to KPCA intrusion detection system under the environment of MATLAB,the result indicates KPCA can well lower the dimensions of the data,and can keep the higher detection rate,suitable for network intrusion detection system to have relatively complicated data source and to have the data of nonlinear characteristic.
