Possible bug in X-Means parameters.

Hello, World!

I was explaining something with集群ing with k-Means, and my XML looked like this (Notice that I'm using theOperator Toolbox扩展,因为我懒得打开Excel my examples):
















<参数键= " parse_all_as_nominal" value="true"/>


























































Pay attention to theClusteringoperator: it hasadd cluster attributechecked andadd as labelas well, and it does add a集群attribute with alabel的角色。

Then I tried to switchk-MeansbyX-Means:
















<参数键= " parse_all_as_nominal" value="true"/>



























































The thing is: if I check theadd cluster attributeit adds the集群attribute like it says it will, but, and here is the report: if I checkadd as label, it doesn't add the集群attribute with alabelrole, but actually it adds thelabel属性。我不得不put aSet Roleoperator after theX-Meansoperator to actually get a label and feed theDecision Tree.

Is this a desired behavior? If so, why? It's counterintuitive.

All the best,

Rodrigo.

    Hi there,

    Update: in RapidMiner 9.0 Beta, now it doesn't change the name集群bylabelyet the model still doesn't make use of theadd as labelcheckbox. To use the cluster as a label (e.g. to interpret results with a decision tree, which is my favourite trick under the sleeve), I need to applySet Roleagain. 50% of the bug/feature has been resolved.





































    Is there anything I can do to help?

    All the best,

    Rodrigo.
