METHOD AND SYSTEM FOR DARA CLUSTERING USING RELATIVE DISTANCE RATE AND DISTANCE BETWEEN CLUSTER'S MEDOIDS

摘要

According to an embodiment, the data clustering method in consideration of the relative distance ratio between data and the distance between the center data of the cluster, among a plurality of data, includes a plurality of data having the smallest ratio of distances from each of the plurality of data. Selecting the center data of the first cluster from among the clusters of; And for each of the remaining clusters excluding the first cluster, minimizing an evaluation function related to a distance from all selected central data of all clusters including the first cluster and a ratio of distances from each of the plurality of data. And selecting the data as the central data.
