| Abstract: | This paper studies the influence of using different data preprocessing methods on fuzzy c-means clustering results.By preprocessing the international standard data set IRIS and electricity consumers data of different industries in a power company with different preprocessing methods,we use fuzzy c-means clustering algorithm for clustering,and compare and analyze the results of clustering.The results show that when using FCM clustering algorithm for clustering,among the preprocessing methods,used in this pap... |
