"Neural Networks Performance"

mksaad

Hello,

I am trying to measure Neural Networks Performance as training cycles increase. I need to plot cycles vs performance.The problem is the performance values is the same in all training cycles !!!!!  ???  :-\ . are there some thing wrong with my code?

<operator name="Root" class="Process" expanded="yes">
    <operator name="ArffExampleSource" class="ArffExampleSource" breakpoints="after">
        <parameter key="data_file"	value="D:\Users\Motaz\Documents\rm_workspace\sample\weka-data\cpu.arff"/>
        <parameter key="label_attribute"	value="class"/>
    </operator>
    <operator name="ParameterIteration" class="ParameterIteration" expanded="yes">
        <list key="parameters">
          <parameter key="NeuralNet.training_cycles"	value="50,75,100,150,200,300,400,500,600,700,800,900,1000"/>
        </list>
        <operator name="NeuralNet" class="NeuralNet">
            <parameter key="keep_example_set"	value="true"/>
            <list key="hidden_layer_types">
              <parameter key="sigmoid"	value="5"/>
              <parameter key="sigmoid"	value="5"/>
            </list>
            <parameter key="learning_rate"	value="0.3"/>
        </operator>
        <operator name="ModelApplier" class="ModelApplier">
            <parameter key="keep_model"	value="true"/>
            <list key="application_parameters">
            </list>
        </operator>
        <operator name="RegressionPerformance" class="RegressionPerformance">
            <parameter key="relative_error"	value="true"/>
        </operator>
        <operator name="ProcessLog" class="ProcessLog">
            <list key="log">
              <parameter key="cycles"	value="operator.NeuralNet.parameter.training_cycles"/>
              <parameter key="performance"	value="operator.RegressionPerformance.parameter.relative_error"/>
            </list>
        </operator>
    </operator>
</operator>

Thanks,

Hi there Motaz,

I think the error is here

<parameter key="performance" value="operator.RegressionPerformance.parameter.relative_error"/>

All should be fine when you change to value instead.

Good weekend
