Research about Real-valued Negative Selection Algorithm with Variable-sized Detector in Abnormal Detection

对负选择算法异常检测中常用的检测器编码方法、实数值变尺寸检测器的产生过程进行研究的基础上,提出了一种简单有效的增加检测器检测半径的计算方法,并进行了实验。从理论分析和实践上都证明了这种方法的有效性,使用这种算法改进后的检测器可明显提高检测器组对检测空间的覆盖率。

In the paper,the variable-sized detectors used in real-valued negative selection algorithm is briefly introduced at first.Then the variable-sized detector and relative algorithm is studied in vector space,and a simple algorithm,which can increase the detector's radius,is recommended and analyzed.At last,some experiment results are presented. Preliminary results demonstrate that the approach enhance the negative selection algorithm in efficiency and without significant increase in eomplexity.
