A Clustering Method for Data in Cylindrical Coordinates

Table 3

Comparison of performances of the four methods using the iris dataset.

Attributes	cyk-means	Fixed cyk-means	-means	Kernel -means
Sepal length, sepal width, petal length	0.5543	0.6961	0.6569	0.6614
Sepal width, petal length, petal width	0.5627	0.7900	0.7462	0.7590
Petal length, petal width, sepal length	0.4179	0.7114	0.7302	0.7359
Petal width, sepal length, sepal width	0.5171	0.6121	0.6104	0.6099

ARI are the mean of 200 runs with random initial values. The best estimations are bold. “Attributes” indicates three attributes used in clustering.
