2D Data Sets used for the CHAMELEON Clustering Algorithm
Several 2D data sets used to evaluate the CHAMELEON clustering alogrithm in the paper by Karypis et al (1999) and used by iVAT, an ordering-based tool to asses cluster tendency (Havens and Bezdek, 2012).
data(Chameleon)
chameleon_ds4:
The format is a 8,000 x 2 data.frame.
chameleon_ds5:
The format is a 8,000 x 2 data.frame.
chameleon_ds7:
The format is a 10,000 x 2 data.frame.
chameleon_ds8:
The format is a 8,000 x 2 data.frame.
