SYSTEM AND METHOD OF GENERATING INITIAL CLUSTER CENTROIDS

摘要

A computer system includes a processor and a computer-readable storage medium. The computer-readable storage medium has stored therein instructions that when executed by the processor perform a method for generating initial cluster centroids. The method includes generating (Key1, Value1) pairs of input datasets. The method also includes calculating global designated values, among the generated (Key1, Value1) pairs, to be reference values. The method also includes calculating similarity values of the input datasets based on the reference values. The method further includes generating (Key2, Value2) pairs of input datasets. The method further includes generating median similarity value, among the generated (Key2, Value2) pairs, to generate corresponding initial cluster centroids. The Key1 and the Value1 are a feature variable and a feature value, respectively, of corresponding input dataset. The Key2 and the Value2 are the similarity value and the feature value, respectively, of corresponding input dataset.
