Cross entropy clustering

My kids love mickey mouse. πŸ˜‰
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!

plot(  cec.mouse1.spherical )

Mickey mouse !

Next, compare k-means and CEC.


Oh! colorful mickey !!!

Next use CEC.

c <- CEC(k=3, x=dataset, control.nstart=10, method.type='spherical')

The result fits my feeling.

I think CEC is similar to EM based clustering.
