Abstract�� Bezdek type fuzzy attribute C-means clustering algorithm(FAMC) was proposed by extending attribute means clustering(AMC) algorithm based on fuzziness index (or weighting exponent) ��m��. The iterative algorithm was derived and the effect of fuzziness index ��m�� on objective function convergence was discussed. The experimental results of pattern recognition performances on standard Iris database and tumor/normal gene chip expression data demonstrate that FAMC is more effective than fuzzy C-means clustering(FCM) algorithm and AMC.
Keywords�� fuzzy C-means clustering   attribute means clustering   stable function   gene expression data
