Artificial Immune System(AIS) are intelligent computational systems evolved using theories of the human immune system. Our immune system is naturally self organising and adaptive. It has continually inspired the computational research especially as the problems are getting more intricate. Different perspectives can help build solution for complex problems pertaining to machine learning, classification, anomaly detection. This overview undertakes the exploration of the remarkable features of the human system that is motivating the researchers to build Artificial Immune System based intelligent classification models. It’s a promising area providing substantial diversity.
