- Abstract:
-
The clustering validity index can be used to evaluate the effectiveness of clustering results and determine the number of clusters. However, existing validity indices for fuzzy c-mean algorithm suffer from the inadequate characterization of intracluster compactness and inaccurate measurement of intercluster separability. To address these issues, we proposed a new fuzzy clustering validity index called maximum-mean (MAME), which considers the maximum and mean values and is designed based on two perspectives, intracluster compactness and intercluster separability. First, considering the comprehensive characteristics of the entire dataset, a new expression of fuzzy compactness measure is put forward by calculating the ratio of cases divided into K clusters and one cluster, respectively. Second, by introducing the maximum and mean distance between cluster centers, a new method is proposed for separability measurement. Finally, the MAME index is put forward on the strength of fuzzy compactness measure expression and the separability measure method. Using five UCI and six artificial datasets, MAME is compared with nine other cluster validity indices, including CH, DB, NPC, PE, FSI, XBI, NPE, WLI, and I. The experimental results demonstrate the accuracy and stability of our proposed index, indicating that MAME has good robustness.
