K-means, and self-organizing map and the feature selection methods based on coefficient of variation and simple T-test were integrated. To evaluate the performance of the Samcluster system, the Samcluster was applied to four expression datasets COLON, LEUKEMIA72. LEUKEMIA38, and OVARIAN. The results show that there are only 5, 1,0, and 0 samples misclassified, respectively. We conclude that the proposed scheme. SamCluster. is an efficient method for automatic discovery of sample classes using gene expression profile.
