Abstract—Clustering Categorical data is more complicated process than numerical clustering. In this paper the traditional K-Modes algorithm is extended with the weighted measure based on the probability of respective matching attribute value in the data set. The proposed method is experimented with the data sets obtained from UCI data repository. Results prove that the proposed weighted measure is superior to K-Modes.
