Artificial Immune System

Artificial immune system (AIS) is a computational intelligence system inspired by the working mechanism and principle of biological immune system (BIS). BIS makes use of innate immunity and adaptive immunity systems to generate accurate immune response against the invading antigens. The two systems mutually cooperate to resist the invasion of external antigens. The key to designing the AIS is to take full advantage of the immunology principles and to replicate the effectiveness and capability of the BIS in computer systems. Most of the AISs and malware detection methods have some deficiencies and shortcomings, which stimulates researchers to explore more efficient models and algorithms, including negative selection algorithm, clonal selection algorithm, immune network model, Danger theory, and immune concentration. At present, AIS has been widely used in many fields such as pattern recognition, function optimization, computer security, robot control, and data analysis.
