ClusterDensityEvaluator

Shubha

Hi,

I was working with the operator, "ClusterDensityEvaluator", with the below code.

<operator name="Root" class="Process" expanded="yes">
    <operator name="ExampleSetGenerator" class="ExampleSetGenerator">
        <parameter key="target_function"	value="sum classification"/>
        <parameter key="number_examples"	value="200"/>
        <parameter key="number_of_attributes"	value="2"/>
    </operator>
    <operator name="KMeans" class="KMeans">
    </operator>
    <operator name="ClusterDensityEvaluator" class="ClusterDensityEvaluator" breakpoints="before">
    </operator>
</operator>

But the "ClusterDensityEvaluator" operator needs the SimilarityMeasure operator also to make it work. What 'SimilarityMeasure' is this? I meant the similarity measure from what to what?

Thanks for your help,
Shubha

Hi,
this SimiliarityMeasure contains informations about the distance between each two examples. The below code will provide a SimiliarityMeasure

<operator name="Root" class="Process" expanded="yes">
    <operator name="ExampleSetGenerator" class="ExampleSetGenerator">
        <parameter key="target_function"	value="sum classification"/>
        <parameter key="number_examples"	value="200"/>
        <parameter key="number_of_attributes"	value="2"/>
    </operator>
    <operator name="ExampleSet2Similarity" class="ExampleSet2Similarity">
    </operator>
    <operator name="KMeans" class="KMeans">
    </operator>
    <operator name="ClusterDensityEvaluator" class="ClusterDensityEvaluator">
    </operator>
</operator>
