Fuzzy Clustering of Categorical Attributes and its Use in Analyzing Cultural Data

Year: 2007 Volume: 1 Issue: 1 220 - 224 Pages

Abstract: We develop a three-step fuzzy logic-based algorithm for clustering categorical attributes, and we apply it to analyze cultural data. In the first step the algorithm employs an entropy-based clustering scheme, which initializes the cluster centers. In the second step we apply the fuzzy c-modes algorithm to obtain a fuzzy partition of the data set, and the third step introduces a novel cluster validity index, which decides the final number of clusters.
