56660 否定选择算法(negative selection algorithm, NSA)是人工免疫系统的核心基础算法. The negative selection algorithm (NSA) is the key algorithm of the artificial immune system.
56661 孔洞是引起NSA检测率低的重要因素. Thehole is an important factor that causes low detection rates of NSAs.
56662 传统NSA未考虑孔洞的分布,采取在特征空间内通过完全随机的方式盲目生成检测器以修复孔洞,导致孔洞修复效果不佳,并且淘汰无效的检测器也异常耗时. Traditional NSAs do not consider holedistribution. To eliminate holes, detectors are randomly generated in the feature space; however, this approachis ineffective, and eliminating invalid detectors is also time consuming.
56663 孔洞问题在生物免疫系统中也同样存在. The hole problem also exists in thebiological immune system, in which the MHC molecules are used to handle the hole problem.
56664 生物免疫系统利用MHC分子针对孔洞产生的特殊形态,对免疫细胞的发育过程进行限定,从而训练出覆盖孔洞的免疫细胞,进而解决孔洞问题.受此启发,本文提出一种基于免疫MHC的否定选择算法——孔洞修复方法 MHC-NSA. Inspired by thefunction of MHC, a hole improvement method, namely, the MHC-NSA method, is proposed.
56665 首先以训练样本生成的维诺图(Voronoi)对形态空间进行划分,利用维诺图的最邻近特性,在维诺图中两类点处快速生成两类检测器,以较小训练代价达到对非自体空间较好的覆盖; First, the featurespace is divided by Voronoi, and two types of detectors are generated at two points in Voronoi.
56666 其次模拟MHC针对孔洞所具有的特殊形态,对所产生的孔洞位置进行定位,并限定该位置生成孔洞修复检测器,从而提升孔洞修复效果. Second, the holeimprovement detectors are directly generated at the holes by positioning the holes.
56667 理论分析表明,MHC-NSA所生成的孔洞修复检测器可将孔洞最高占比降低62.8% Theoretical analysis showsthat the hole improvement detectors can reduce the highest percentage of holes by 62. 8%.
