Parallel execution of operators

Legacy User

Ok thanks.

Is it possible to apply operator in "parallel" ? I would like to filter input data that have RESULT A and RESULT B.
INPUT -> OPERATOR A -> RESULT A
INPUT -> OPERATOR B -> RESULT B

Operator seems to be chained in series:
INPUT -> OPERATOR A -> OPERATOR B -> RESULT C.

Hi,

first of all: I hope you don't mind I put your questions in separate threads. That way, all users can easily recognize separate questions ...

Regarding your problem, yes, in general operators in the operator tree are executed as a chain. However you can achieve a setting like the one you mentioned by using loops, e.g. by applying the [tt]ParameterIteration[/tt] operator.

Here is an example process:

<operator name="Root" class="Process" expanded="yes">
    <operator name="ExampleSetGenerator" class="ExampleSetGenerator">
        <parameter key="target_function"	value="simple polynomial classification"/>
    </operator>
    <operator name="ParameterIteration" class="ParameterIteration" expanded="yes">
        <parameter key="keep_output"	value="true"/>
        <list key="parameters">
          <parameter key="OperatorSelector.select_which"	value="1,2"/>
        </list>
        <operator name="OperatorSelector" class="OperatorSelector" expanded="yes">
            <parameter key="select_which"	value="2"/>
            <operator name="ExampleFilter" class="ExampleFilter">
                <parameter key="condition_class"	value="attribute_value_filter"/>
                <parameter key="parameter_string"	value="att1&gt;0"/>
            </operator>
            <operator name="ExampleFilter (2)" class="ExampleFilter">
                <parameter key="condition_class"	value="attribute_value_filter"/>
                <parameter key="parameter_string"	value="att1&lt;0"/>
            </operator>
        </operator>
    </operator>
</operator>

Hope that helps,
regards,
Tobias
