摘要
针对免疫机制的入侵检测系统中实值检测器的维数灾难问题,借鉴信息熵理论,提出一种基于熵的实值检测器降维优化算法,使检测器在保留足够信息量的前提下在低维空间中运行,有效提高检测效率.实验表明,降维后的检测器表现出更好的检测性能.
In order to deal with the "dimension curse" problem of real-valued detector in immunity-based intrusion detection system,we borrowed ideas from the information entropy theory,and a real-valued immune detector dimension-reducing optimization algorithm is proposed in this paper.The optimized detectors can retain the most useful information and work in the low-dimensional shape-space,which can improve the detection efficiency.The experiments show that the dimension-reduced detectors have better detector performances.
