Abstract: By analyzing the reasons for the low detection rate of the existing real-value negative selection algorithms, an improved negative selection algorithm is proposed with the identification of boundary samples to improve the coverage of holes. Detailed realization and advantages of the algorithm are given. The experiments of synthetic 2DSyntheticData and real biomedical data sets are done to test the algorithm. Experimental results show that the algorithm has higher detection rate and needs less detector numbers. It has optimum overall performance.
