X-Cobweb problem

Hi,

Can somebody help to understand why the X-Cobweb algorithm won´t work just like it does in Weka? I´m trying to cluster the classic zoo.arff data set. In Weka works fine but in RapidMiner it shows each instance in a separate cluster.

Thanks in advance

Hey @Lisi ,
could you please share the process or at least the parameters which are set for the clustering?

Hi. Yes, of course.

The process consist of a readArff Operator (which reads the file zoo.arff) and the output port of this operator connects to a W-Cobweb Operator with the Following parameters:

- A: 1.0
- C: 0.0028
- S: 4.2

This last operator uses both outputs and connect them to res.

I attach the output from RapidMiner and what I get from Weka.

Hello

Did you check some settings in weka and rapidminer?( I mean that both of them in the setting of process should be the same. Most of the time people forget to check them.)

So please check all options of process in both software then if you see the problem again send your process and data in order we can check it again.

Thank you
