- 摘要：It is very common that flow distribution of class is not uniform in attack traffic. It wi11 lead to a 1ow classification accuracy in network intrusion detection. For overcoming this class imbalance phenomenon，a pipelining ensemble approach in different feature spaces was proposed，which translates multi-class classification to two-class classification.
