Abstract:

An analysis method of gene expression data based on immnue clustering algorithm is presented. A modified consine coefficient is put forward to measure comparability of genes in accordance with the characteristic of gene expression data matrix. Inspired by the biology immune system,a new clustering algorithm based on immunodominance cloning(ICCA) is designed. In comparison with Kmeans algorithm and genetic Kmeans algorithm, the proposed ICCA given can achieve good class compactness and separability. 
