Data clustering method, information processing apparatus, and data clustering program

摘要

PROBLEM TO BE SOLVED: To prevent degradation of accuracy in streaming clustering.SOLUTION: In a data clustering in streaming clustering processing, an information processor 1 executes a processing including the steps of: dividing a feature space in which input data points are disposed into grids; determining a representative point independently to each of grids in which one or more data points are included (S17); and when any data point is added to a grid including a representative point, weighting based on the representative point and to added a data point to determine a new representative point (S18), to thereby control the number of the clusters using the new representative point.SELECTED DRAWING: Figure 9
