Fuzzy relation degree and cluster validity

Fan Jiulun Pei Jihong Xie Weixin (School of Electronic Engineering, Xidian Univ., Xian, 710071)  
Based on the geometrical structure of a data set, the fuzzy relation degree between classes of fuzzy partition is introduced and a cluster validity function is presented. Experimental results show the effectiveness and robustness of this cluster validity function.
