Abstract:

This paper discusses the fuzzy C-means algorithm（FCM） , one of the fuzzy clustering methods and clustering validity measurements. Considering the characteristics of microarray, we design and realize a FCM model based on clustering validity functions. We apply the model to the gene expression data ofleukaemia and gain a good result which is close to the fact.

Key words: （gene expression data, fuzzy clustering, FCM;clustering validity, Xie-Beni index）
