The new method formulas the immune response as a quaternion AIR=(G,I,R,A), where G denotes exterior stimulus or antigen, I denotes the set of valid antibodies, R denotes the set of reaction rules describing the interactions between antibodies, and A denotes the dynamical algorithm describing how the reaction rules are applied to antibody population. In order to solve unsupervised classification problems, the new method encodes each antibody as a sequence of real integer numbers representing the cluster representatives, and searches the optimal cluster representatives from a combinatorial optimization viewpoint using the dynamical algorithm A. The experimental results on six artificial datasets with different manifold structure and the USPS handwritten digit datasets show that the novel algorithm has the ability to identify complex non-convex clusters compared with the K-Means algorithm, a genetic algorithm-based clustering proposed by Maulik, and a evolutionary clustering algorithm with the manifold distance. Key words Artificial immune systems, manifold, unsupervised classification, clustering, pattern recognition.
