Abstract: Using support vector machine(SVM) active learning in intrusion detection to resolve the problem of machine learning in the small sample size. This paper provides a framework of intrusion detection system based on SVM active learning, and it also provides a SVM active learning algorithm for intrusion detection system, discusses how the composition of the unlabeled sample set, the size of the unlabeled sample set and the parameter of the kernel function affect the accuracy of the SVM. Compared with the traditional SVM self-learning algorithm, the experiment shows active learning algorithm can immensely reduce the number of the training date and efficiently improve the performance of the classifier in intrusion detection system.
