Artificial immune system An artificial immune system (AIS) is a type of optimisation algorithm inspired by the principles and processes of the vertebrate immune system. The algorithms typically exploit the immune system's characteristics of learning and memory to solve a problem. ..... Click the link for more information. (AIS) is an adaptive system An adaptive system is a system that is able to adapt its behavior according to changes in its environment or in parts of the system itself. A human being, for instance, is certainly an adaptive system; so are organizations and families. inspired from
immunology immunology, branch of medicine that studies the response of organisms to foreign substances, e.g., viruses, bacteria, and bacterial toxins (see immunity). Immunologists study the tissues and organs of the immune system (bone marrow, spleen, tonsils, thymus, lymphatic and immune phenomena, to implement the immune model,
principles, and functions through humans or computers (Cai & Gong,
2002). This technology has recently been advancing rapidly, and has
shown the strong robustness for processing information and powerful
ability to solve complex problems. The research evolved from immunology
in the middle 1980s. In 1990, Bersini first used immune algorithms to
solve problems in the adaptive network (Bersini & Varela. 1991).
Meanwhile, Ishida (1990) used the artificial immune system to solve the
fault diagnosis problem of the sensor network A low-speed industrial network that is used to connect sensors to actuators. A sensor network implies limited or no controller functions. Multiple sensor networks may be coupled to form device networks. See industrial control network. . In 1994, Forrest,
Perelson, Allen, and Cherukuri first applied immune algorithms to
computer security and virus detection (Dasgupta & Forrest, 1998). In
1995, Cooke and Hunt began to apply immune algorithms to the machine
learning field. In 2002, Gong and Cai first proposed the multi-dimension
immune network, used the immune mechanism to solve the security problem
of the education network, and investigated the relations between
robustness and immunity, then Gong (2003) investigated the
multi-dimension education immune agent in his master thesis, and
discussed how to use the immune computation techniques to build a new
e-learning system. Recently, AIS is regarded as a new and good technique
to solve web problems, like network security and fault diagnosis (Castro
& Timmis, 2002).
