log the exampleset size?


I'm using the DatabaseExampleSource to create an ExampleSet. Is there a way to log how many examples there are in the ExampleSet?

I didn't see anything in ProcessLog or a forum search.

Thanks,
Gary

Re: log the exampleset size?

Hi there,

Indeedy, the documentation can be, shall we say, a liitle patchy... But I know there are moves afoot to put this right, so in the meantime I hope this helps ( look in the process log table view )...

<operator name="Root" class="Process" expanded="yes">
    <operator name="ExampleSetGenerator" class="ExampleSetGenerator">
        <parameter key="target_function" value="random"/>
    </operator>
    <operator name="DataMacroDefinition" class="DataMacroDefinition">
        <parameter key="macro" value="Bla"/>
    </operator>
    <operator name="ProcessLog" class="ProcessLog">
        <list key="log">
          <parameter key="Examples" value="operator.DataMacroDefinition.value.macro_value"/>
        </list>
    </operator>
</operator>
