Table 1

Thin contrast of DataSet1.

	Serializing; 𝑘-means	Clara	RICA	Parallel; 𝑘-means	GCPK
Cluster (𝑘)	5	5	5	5	5
Average; phase thin	23.2027	21.8868	19.0924	16.0240	16.0226
Maximum; phase thin	105.2276	113.2348	96.5631	78.2311	77.3419
Abnormal; finding	83.22%	89.36%	89.53%	93.23%	93.3%

Note: the average phase thin and maximum phase thin are the mean values of each cluster.
