My kids love mickey mouse. ;-)
If you have mickey mouse plot, can you cluster the data reasonably ?
R package named gmum.r provides interesting solution to do it.
The package has many features for data analysis. If reader who has interest it please use it.
I used the package to cluster mickey mouse data!
library(gmum.r) data("cec.mouse1.spherical") plot( cec.mouse1.spherical )
Next, compare k-means and CEC.
c <- CEC(k=3, x=dataset, control.nstart=10, method.type='spherical') plot(c)
I think CEC is similar to EM based clustering.
