The proposed QBS filter applies the concepts of data quantization to signal processing in order to develop a novel classification system. Through interaction with a partially trained classifier the QBS filter can use an oracle to produce high-quality training data. We tested the method with a benchmark intrusion dataset to verify its performance and effectiveness. Results show that selecting qualified training data will have an impact not only on the performance but also on overall execution to reduce distortion . This method can significantly increase the accuracy of the detection rate for suspicious activity and can recognize rare attacks. Additionally the method can improve the efficiency of real-time intrusion detection models. Copyright 2009 Liang-Bin Lai et al.
