SYSTEM AND METHOD OF GENERATING INITIAL CLUSTER CENTROIDS
First Claim
1. A method of generating initial cluster centroids using a processor, comprising:
- using the processor, generating (Key1, Value1) pairs of input datasets;
using the processor, calculating global designated values, among the generated (Key1, Value1) pairs, to be reference values;
using the processor, calculating similarity values of the input datasets based on the reference values; and
using the processor, generating median similarity values based on the similarity values of the input datasets to generate corresponding initial cluster centroids,whereinthe Key1 and the Value1 are a feature variable and a feature value,respectively, of corresponding input dataset;
the processor runs the steps of generating (Key1, Value1) pairs, the steps of calculating global designated values, the steps of calculating similarity values and the steps of generating median similarity values by executing a set of instructions storing in a machine readable storage medium.

Abstract
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.
