    Hi,
    since version 4.3 the cluster characterizer has been removed, since its easyly possible to use any learning algorithm to characterise your clusters. I will post a simple example process below: 
    <operator name="Root" class="Process" expanded="yes">
        <operator name="ExampleSetGenerator" class="ExampleSetGenerator">
            <parameter key="number_of_attributes"	value="2"/>
            <parameter key="target_function"	value="gaussian mixture clusters"/>
        </operator>
        <operator name="KMeans" class="KMeans">
            <parameter key="k"	value="3"/>
        </operator>
        <operator name="ChangeAttributeRole" class="ChangeAttributeRole">
            <parameter key="name"	value="cluster"/>
            <parameter key="target_role"	value="label"/>
        </operator>
        <operator name="RuleLearner" class="RuleLearner">
        </operator>
    </operator>
    Hope this helps.

    Greeting,
      Sebastian

    Hi, I have tried it. thank you.
    As a beginner, I have still a question.
    In old AttributeSumClusterCharacterizer node, it provides the visibility of showing N words that represent every cluster.
    How can I do it now?

    May it is not so clear, but its a shame that I didn't save the old pictures of the analysis
    e.g. old AttributeSumClusterCharacterizer node reults in Text view

    Cluster Model
    Cluster 0 [xxx, swe, ower]: 6 items
    Cluster 1 [soliw, wo, sow]: 2 items
    Cluster 2 [wepoi, soawer, aowe]: 4 items
    Cluster 3 [aoiwer,aiwoer ioser]: 2 items

    Total number of items: 14

    but now

    Cluster Model
    Cluster 0: 6 items
    Cluster 1: 2 items
    Cluster 2: 4 items
    Cluster 3: 2 items

    Total number of items: 14

    And I find the processing time is rahter long for RuleLearner.
    How can I get the Characteristic words now?

    During the processing, I get two Warnings, Why?  :-\
