Classification: CPC G  Y | IPC G

Claim 9:
10. The clustering device according to claim 8, wherein
the clustering section includes a centroid calculation circuit configured to calculate a cluster centroid for each cluster when classifying the multiple element data into clusters,
the centroid calculation circuit includes:
a data adder configured to add element data within each cluster to obtain a data addition value;
a quantity calculator configured to calculate the number of element data within each cluster from a number of signals corresponding to element data within each cluster;
a first register configured to hold the data addition value obtained by the data adder;
a second register configured to hold the number of element data obtained by the quantity calculator; and
a divider configured to divide the data addition value held in the first register by the number of element data held in the second register to calculate the cluster centroid, wherein

the evaluation score calculation section is configured to:
calculate, for each cluster, the second index value using the data addition value acquired by the first register and the number of element data acquired by the second register; and
calculate the evaluation score using the second index value for each cluster.
