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 )
Mickey mouse !
Next, compare k-means and CEC.
k<-kmeans(cec.mouse1.spherical,10) plot(cec.mouse1.spherical,col=k$cluster)
Oh! colorful mickey !!!
Next use CEC.
c <- CEC(k=3, x=dataset, control.nstart=10, method.type='spherical') plot(c)
The result fits my feeling.
I think CEC is similar to EM based clustering.
