PROBLEM TO BE SOLVED: To cluster input data appropriately.SOLUTION: A clustering method for determining a class to which each of multiple pieces of input data belongs includes: calculating a distance between the input data and each of multiple pieces of representative data; selecting a distance calculation method on the basis of the input data; and causing the input data to belong to representative data with the shortest distance calculated in a calculation step by use of the selected distance calculation method.SELECTED DRAWING: Figure 1 |
