Hello
I would like to know what kind of KMedoids Algorithm using in RapidMiner?
Is it PAM? CLARA? or other?

thanks 

Ann


Answer by Anonymous:

I am not programmer but I think It is PAM (Partitioning Around Medoids) 'cause it's another name for same thing. That's a pity there isn't any CLARA and CLARANS. Strange is that I can't see any computing of medians in PAM. But robusteness is about that you change computing from mean (k-means) to median and outliers can't change location of center in cluster as rapidly as in k-means.

    Hello,

    does somebody know if this is correct. Is it the PAM Algorithm used for K-medoid also in version 7.5 ?

    thanks

    No, it is not the well-known PAM algorithm. Its an inferior algorithm. It also appears to be restricted to coordinate data.
