Network Intrusion Detection Based On LSSVM Improved by Sparrow Search Algorithm
The performance of the Least Squares Support Vector Machine model in network intrusion detection is directly affected by the penalization parameters,so a network intrusion de-tection model based on LSSVM model is improved by sparrow search algorithm for higher accura-cy.Compared with PSO-LSSVM model,GA-LSSVM model,GWO-LSSVM model and LSSVM model,the SSA-LSSVM model has the highest accuracy of network intrusion detection.SSA-LSSVM can achieve high-precision network intrusion detection,and provide decision-making ba-sis for network security maintenance and enhance intrusion detection function.
