A Hybrid Swarm Intelligence Algorithm for Intrusion Detection Using Significant Features

Algorithm 3

Random feature selection method.

Input: Dataset with Features

Output: Vital features

Begin

   Let = , where represents the number of features in the dataset

 Let =

   : do

    Delete from

      //update feature subset

  Apply SVM classifier

  Delete from

end

Sort the features based on classifier accuracy (acc)

If acc > acc_threshold and detection rate > dr_threshold then

    //selecting vital features

End
