Class WekaAggregateEvaluations

  • All Implemented Interfaces:
    adams.core.AdditionalInformationHandler, adams.core.CleanUpHandler, adams.core.Destroyable, adams.core.GlobalInfoSupporter, adams.core.logging.LoggingLevelHandler, adams.core.logging.LoggingSupporter, adams.core.option.OptionHandler, adams.core.QuickInfoSupporter, adams.core.ShallowCopySupporter<adams.flow.core.Actor>, adams.core.SizeOfHandler, adams.core.Stoppable, adams.core.StoppableWithFeedback, adams.core.VariablesInspectionHandler, adams.event.VariableChangeListener, adams.flow.core.Actor, adams.flow.core.ErrorHandler, adams.flow.core.InputConsumer, adams.flow.core.OutputProducer, Serializable, Comparable

    public class WekaAggregateEvaluations
    extends adams.flow.transformer.AbstractTransformer
    Aggregates incoming weka.classifiers.Evaluation objects and forwards the current aggregated state. Only works with the predictions stored in the evaluation object. NB: Relative absolute error and Root relative squared error will differ a bit.

    Input/output:
    - accepts:
       weka.classifiers.Evaluation
    - generates:
       weka.classifiers.Evaluation


    Valid options are:

    -D <int> (property: debugLevel)
        The greater the number the more additional info the scheme may output to
        the console (0 = off).
        default: 0
        minimum: 0
     
    -name <java.lang.String> (property: name)
        The name of the actor.
        default: WekaAggregateEvaluations
     
    -annotation <adams.core.base.BaseText> (property: annotations)
        The annotations to attach to this actor.
        default:
     
    -skip (property: skip)
        If set to true, transformation is skipped and the input token is just forwarded
        as it is.
     
    -stop-flow-on-error (property: stopFlowOnError)
        If set to true, the flow gets stopped in case this actor encounters an error;
         useful for critical actors.
