Network intrusion detection system has gained attention as an effective means of combating various cyber threats. However
there are a lot of redundant information and unbalanced distribution problems in network intrusion data
therefore
deep learning and support vector machine-recursive feature elimination-based network intrusion detection model (DLRF) was proposed. The features were sorted by the support vector machine-recursive feature elimination algorithm and the important features were selected. Moreover
both oversampling and under-sampling techniques were utilized to tackle the unbalance problem of data sample distribution. Three deep learning algorithms were used to build the base learner of the ensemble framework
and deep neural network was used to build the meta-learner
so as to improve the performance of DLRF model to detect network attacks. The proposed framework was experimented with two publicly available and popular network traffic datasets
namely UNSW-NB15 and CICIDS-2017. The accuracy rates of the DLRF model on these two datasets are 0.906 8 and 0.996 8 respectively
