APPARATUS AND METHOD FOR CLUSTERING USING MUTUAL INFORMATION BETWEEN CLUSTERS

摘要

PURPOSE: An apparatus and a method for clustering using mutual information between clusters are provided to classify the data without information about the number of clusters. CONSTITUTION: An initial value determination unit(110) determines a data spot with maximum density value as an initial clustering center. The initial density value is calculated based on the distance information between data points in a data set. A cluster center determination unit(120) determines the cluster centers which classifies the data set into clusters based on the density value of the data spots. A mutual information output unit(130) outputs the mutual information value which expresses the relation between the clusters based on the distance information between the cluster center and the data spot.
