PROBLEM TO BE SOLVED: To provide a method of dividing data points acquired from a sensor into clusters in industrial usage and a method of processing based upon a graph for signal noise removal, etc.SOLUTION: A data point 301 of input data is processed 310 by finding a Laplacian matrix of the data first. A spectrum of the Laplacian matrix includes an attraction spectrum having a positive characteristic value, a repulsion spectrum having a negative characteristic value, and a neutral spectrum having a characteristic value of 0. An operation for processing is determined 320 using the Laplacian matrix and also using information associated with the attraction spectrum, repulsion spectrum, and neutral spectrum. The information includes those spectra and properties derived from those spectra. Then the determined operation is executed 330 and processed data 302 is generated. |
