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
