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

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

    </operator>
    <operator name="ModelLoader" class="ModelLoader">
        <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?

bennie

now my output is correct
tried it again and it worked dunno what i did wrong

Hi,
anyway, if you just start to work with RapidMiner, I would suggest to switch directly to RapidMiner 5.0. It will help you a lot on such problems, since the automatic meta data checking will indicate errors before executing the process and will offer Quickfixes if possible, which solve the problem.


By the way: If you just started, how did you received RapidMiner? Did you download explicitly RapidMiner 4.6 on source forge?
