Abstract: A network anomaly detection method based on one-class SVM and active learning was presented. Firstly, the original instances were used to trained an one-class SVM model in unsupervised manner. Then the instances which can improve the performance mostly were found by active learning strategy. Finally, the classify model was retrained in semi-supervised manner with both labeled and unlabeled data. The experiment results demonstrate that the presented method can improve performance with a small amount of labeled data and reduce the cost of labeling through active learning. It is more feasible to be used in real network environment.
