Classification: CPC G  Y | IPC G

Claim 10:
11. A clustering method, comprising:
a batch process step of obtaining an optimum number of clusters from evaluation scores obtained by classifying all element data into clusters while changing a number of clusters to evaluate classification results for each of the number of clusters, obtaining a classification result of classifying all element data into clusters with the optimum number of clusters, and causing switching between enabling and disabling a latch operation of at least one pair of cells respectively provided in two register sections, whereby the latch operation of the at least one pair of the cells are controlled concurrently;
an update process step of assigning, upon addition of new element data after the batch process step, the new element data to one of existing clusters, and calculating an evaluation score for evaluating a classification result after assigning the new element data to the one of the existing clusters; and
a determining step of determining validity of the classification result after assigning the newly added element data to the cluster in the update process step, by comparing the evaluation score obtained by assigning the newly added element data to the cluster in the update process step and the evaluation score before assigning the newly added element data to the cluster.
