摘要: 针对传统免疫网络分类算法在记忆细胞确定上缺乏有效的指导,该文提出一种基于动态识别邻域的免疫网络分类算法。算法采用核函数表示机制来描述抗体-抗原之间的亲和度;利用抗原对构造动态识别邻域来指导抗体群体的进化,并选择邻域中距离对偶抗原最近的抗体为记忆细胞。算法被应用于多分类问题及高维分类问题来进行算法性能分析,同时,算法被应用于多个标准数据集的分类来评估算法的整体性能。分类结果表明该算法对于标准测试数据集有良好的分类性能,这说明基于动态识别邻域的训练方法能够有效地指导记忆细胞的生成,显著地改善分类器的性能。Abstract: For lack of effective methods used by the traditional immune network algorithms to guide the memory cell determination, a dynamic recognition neighborhood based immune network classification algorithm is proposed. The algorithm uses a kernel function representation scheme to describe the antibody-antigen affinity, and constructs dynamic recognition neighborhood with using pair wise antigens to guide the antibody population evolution, in which the antibody nearest to the pairing antigen is determined as the memory cell. The algorithm is applied to multi-class problem and high dimensional classification problem to analyze the classification performance. Furthermore, the algorithm is used for many standard datasets classification to evaluate the algorithm overall performance. The results show that the proposed algorithm can achieve better classification performance, which indicates that the dynamic recognition neighborhood based training method is able to guide the memory cell generation effectively and improve the algorithm performance significantly.
