In order to improve the network security intrusion detection accuracy
proposes a quantum particle swarm optimization (QPSO) optimized least square support vector machine (LSSVC) network anomaly detection method (QPSO-LSSVC) .The first use of the quantum particle swarm algorithm for the parameters of LSSVC model search
optimal parameters
and then the generalization ability of excellent LSSVC modeling and detection for network intrusion.Select the KDDCUP99 data on QPSO-LSSVC performance testing
the experimental results show that
QPSO-LSSVC improves the network anomaly detection accuracy
reduce the rate of false positives
provides effective guarantee for network security.
