Newb: Can't get a Training and Test Set working with EvoSVM

bennie

Hi Guys,

i'm trying for hours to get a training set and test some unlabeled data to that set. i read the tutorial and searched the forum but i can't get it working

i created two processes. the first should create my training set and the second give my an output for what my testdata is classified into.

1)

 
<operator name="Root" class="Process" expanded="yes">
    <operator name="ExampleSource" class="ExampleSource">
        <parameter key="attributes"	value="C:\Users\Admin\Documents\rm_workspace\SDNN5Min.aml"/>
    </operator>
    <operator name="XValidation" class="XValidation" expanded="yes">
        <parameter key="create_complete_model"	value="true"/>
        <parameter key="number_of_validations"	value="2"/>
        <parameter key="sampling_type"	value="shuffled sampling"/>
        <operator name="EvoSVM" class="EvoSVM">
        </operator>
        <operator name="OperatorChain" class="OperatorChain" expanded="yes">
            <operator name="ModelApplier" class="ModelApplier">
                <list key="application_parameters">
                </list>
            </operator>
            <operator name="Performance" class="Performance">
            </operator>
        </operator>
    </operator>
    <operator name="ModelWriter" class="ModelWriter">
        <parameter key="model_file"	value="C:\Users\Admin\Documents\rm_workspace\Train_SDNN5Min.mod"/>
    </operator>
</operator>

and

<operator name="Root" class="Process" expanded="yes">
    <operator name="ExampleSource" class="ExampleSource">
        <parameter key="attributes"	value="C:\Users\Admin\Documents\rm_workspace\test.aml"/>
    </operator>
    <operator name="ModelLoader" class="ModelLoader">
        <parameter key="model_file"	value="C:\Users\Admin\Documents\rm_workspace\Train_SDNN5Min.mod"/>
    </operator>
    <operator name="ModelApplier" class="ModelApplier">
        <list key="application_parameters">
        </list>
    </operator>
    <operator name="ExampleSetWriter" class="ExampleSetWriter">
        <parameter key="example_set_file"	value="C:\Users\Admin\Documents\rm_workspace\asd.dat"/>
    </operator>
</operator>

My input data is for the trainingset (first column = Attrib, second = label )
0.022826,1
0.044986,1
0.037715,1
0.034799,1

i kinda edited my process to ( stolen by http://rapid-i.com/rapidforum/index.php/topic,1659.0.html )

<operator name="Root" class="Process" expanded="yes">
    <operator name="Trainingset" class="ExampleSource">
        <parameter key="attributes"	value="C:\Users\Admin\Documents\rm_workspace\SDNN5Min.aml"/>

        <parameter key="create_complete_model"	value="true"/>
        <parameter key="number_of_validations"	value="2"/>
        <parameter key="sampling_type"	value="shuffled sampling"/>
        <operator name="OperatorChain" class="OperatorChain" expanded="yes">

            </operator>
        </operator>
        <operator name="OperatorChain (2)" class="OperatorChain" expanded="yes">
            <operator name="ModelApplier" class="ModelApplier">
                <list key="application_parameters">

            </operator>
            <operator name="Performance" class="Performance">

    <operator name="TestSet" class="ExampleSource">

        <parameter key="model_file"	value="C:\Users\Admin\Documents\rm_workspace\TrainSDNN5.mod"/>
    </operator>
    <operator name="ModelApplier (2)" class="ModelApplier">
        <list key="application_parameters">
        </list>
    </operator>
</operator>

the result for the prediction of my test set is from [9.9799 to 9.800]. well what does it mean?
my label was 0 to 1 and now i got 9.800 so its pritty sure to be in class with the label 1? and if it would be 0.5 it would be exaclty between this two classes?
