The data set is picked from KDD Cup 1999 data, which is available at UCI repository. Using the ‘service’ attribute, the second largest subsets is Smtp (95,156 records) with anomaly ratios of 0.03%. This dataset is not the original dataset. This dataset is not the original dataset. The target variable is renamed to "Target" and is relabeled into "Normal" and "Anomaly".
