INTRUSION DETECTION BASED ON WAVELET KERNEL PCA AND DE OPTIMISED EXTREME LEARNING MACHINE
摘要
Abstract
For network intrusion detection,we propose such a method which combines the wavelet kernel PCA and DE optimised extreme learning machine.First,the kernel principal component analysis (PCA)is applied to conduct the nonlinear dimensionality reduction on original data,in order to further improve nonlinear mapping ability of kernel PCA,wavelet kernel function is introduced as its kernel function. Then the extreme learning machine is used for the classification and recognition of the processed data,and the differential evolution (DE) algorithm is used to obtain the optimal initial weights for the unstable performance of the extreme learning machine caused by random selection of initial weights.Experimental results show that the algorithm proposed can effectively improve the recognition rate of intrusion detection and reduce the rates of false positives and false negatives.关键词
