Associative properties of artificial immune systems

The paper concentrates on analyzing associative properties of Artificial Immune Systems (AIS), especially of immunological memory, which is one of the essential characteristics of adaptive immune systems. This memory is able to store and recall patterns when it is required, and can easily categorize new input data. Immunological memory is distributed among the cells in the AIS memory population, and is robust, because when a portion of the memory population is lost, the remaining memory cells persist to produce a response. The major principle behind vaccination procedures in medicine and immunotherapy takes its source from associative character of a cross-reactive memory response of the immune system.
