Abstract: Inspired by intelligence evolution theory,we integrate several AIS(artificial immune system) algorithms,add a new immune mechanism at the higher level of intelligence,and develop a unified multi-level architecture for artificial immune systems.Firstly,from the perspective of intelligent evolution,we describe that the algorithm based on the whole information processing mechanism of immune system has much more computing ability to deal with different information.Then,with regard to a new data analysis algorithm based on the unified AIS architecture,some experimental results are presented and discussed.Finally,we point out that the unified AIS framework is not only able to improve the efficiency of the existing algorithms but also to extend the application domains.
