Hello
I'm using rapidminer version 8.1
I want to calculate the silhouette value for k-means clustering
For this purposeI downloaded the plugin from the following URL:http://korek.name/web/moje-tvorba/rapidminer-clustering_performance_plugin-average_silhouette-cophenetic_coefficient
My process image is as follows:
In this process, the following error occurs:
Does anyone know where the problem is?
thanksregards
Hi,
I don't know that specific extension.
But from the error code my guess would be, that it might require a numerical cluster attribute. What you could try is to add a Nominal to Numerical Operator after the clustered ExampleSet and change the cluster Attribute to unique integers (remember to check "include special attributes").
No guarantee but it might do the trick.
Best,David
hi @livnhn- that looks like a VERY old extension. I would not find it surprising if it produced errors with RapidMiner 8. If you're just trying to do performance calculations with k-means clustering, there are several native operators that can help:
