Can not find AttributeSumClusterCharacterizer Node

Legacy User

in Text-mining AttributeSumClusterCharacterizer Node can not be found with 4.3 version.

Is it replaced by other Node? how can I to solve this problem

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.

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?  :-\
