public class PHMMIterativeEvaluation
extends AbstractPHMMIterativeEvaluation<IterativeHMMPropositionalizer,weka.utils.IterativeEvaluation>
implements ProvenanceSupporter

Cross-validates a classifier on an incoming dataset. The classifier setup being used in the evaluation is a global 'Classifier' actor.

Input/output:
- accepts:
weka.core.Instances
- 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: PHMMIterativeEvaluation
 

-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.
 

-output <weka.classifiers.evaluation.output.prediction.AbstractOutput> (property: output)
    The class for generating prediction output; if 'Null' is used, then an Evaluation
    object is forwarded instead of a String.
    default: weka.classifiers.evaluation.output.prediction.Null
 

-classifier <adams.flow.core.GlobalActorReference> (property: classifier)
    The global PHMM classifier actor to evaluate on the input data.
    default: PHMMClassifier
 

-folds <int> (property: folds)
    The number of folds to use in the cross-validation; use -1 for leave-one-out
    cross-validation (LOOCV).
    default: 10
    minimum: -1
 

-num-iterations <int> (property: numIterations)
    The number of iterations to perform.
    default: 1
    minimum: 1
 

-iteration-step-size <int> (property: iterationStepSize)
    The step size for the iterations.
    default: 1
    minimum: 1
