Data for: Building an Efficient Intrusion Detection System Based on Feature Selection and Ensemble Classifier

This dataset contains the preprocessed subsets of the original NSL-KDD, AWID, and CIC-IDS2017 datasets. First, we selected the subset from the original sets , and the stastic information can bee seen in our paper "Building An Efficient Intrusion Detection System Based on Feature Selection and Ensemble Classifier". Then, we utilized our proposed CFS-BA algorithm to select different features and constructed the different .csv files.
