WHY DOES THE X MEAN CLUSTERING CHANGES THE NUMBERS OF ITEMS IN THE DESCRIPTION ?
I was working on a data set and used the K means and then later tried X means too. Though, its quite interesting to notice that the Number of Items in the Description after running the process is completely doubled on using X means clustering !!! ( whereas it remained the same while using K means)
This really fascinates me. I assume no matter what ever the type of clustering methodology we are using, rapidminer should rather not manipulate the number of items in the description .
*does it have something to do with Overlapping lapping Clustering
Any help would be greatly appreciated !:)
