反向选择模型是人工免疫系统中的经典模型,但存在训练代价高、覆盖率低的问题.危险理论模型是人工免疫系统中新引进的模型,在降低训练代价,提高覆盖率上具有优势.建立人工免疫危险理论模型必须解决的关键问题之一是:在保持人工免疫系统自适应特征的前提下,设计人工抗原提呈细胞.本文从抗原提呈细胞的生物学原理出发,设计了人工免疫系统中的人工抗原提呈细胞,给出单个人工抗原提呈细胞的结构、细胞上Toll样受体的结构,以及人工抗原提呈细胞群体的结构;设计了人工抗原提呈细胞群体的生命周期.初步的实验结果证明所设计的人工抗原提呈细胞具有自适应发现恶意软件的能力.
Reverse selection model is a classic model in artificial immune system, but it has the problem of high training cost and low coverage.Health theory model is a newly introduced model in artificial immune system, which has advantages in reducing training cost and improving coverage. One of the key problems that must be solved in establishing the theoretical model of artificial immune risk is to design artificial antigen-presenting cells under the premise of maintaining the adaptive feature of artificial immune system.In this paper, based on the biological principle of antigen presenting cells, artificial immune Artificial antigen-presenting cells in the system, giving the structure of a single artificial antigen-presenting cell, the structure of a Toll-like receptor on a cell, and the structure of a population of artificial antigen-presenting cells; designing the life cycle of the artificial antigen-presenting cell population Preliminary experimental results show that the designed artificial antigen - presenting cells have the ability to adaptively detect malware.
