public class WekaTrainTestSetEvaluator extends AbstractCallableWekaClassifierEvaluator implements adams.multiprocess.JobRunnerSupporter
Trains a classifier on an incoming training dataset (from a container) and then evaluates it on the test set (also from a container).
The classifier setup being used in the evaluation is a callable 'Classifier' actor.
Input/output:
- accepts:
adams.flow.container.WekaTrainTestSetContainer
- generates:
adams.flow.container.WekaEvaluationContainer
Container information:
- adams.flow.container.WekaTrainTestSetContainer: Train, Test, Seed, FoldNumber, FoldCount, Train original indices, Test original indices
- adams.flow.container.WekaEvaluationContainer: Evaluation, Model, Prediction output, Original indices, Test data
-logging-level <OFF|SEVERE|WARNING|INFO|CONFIG|FINE|FINER|FINEST> (property: loggingLevel) The logging level for outputting errors and debugging output. default: WARNING min-user-mode: Expert
-name <java.lang.String> (property: name) The name of the actor. default: WekaTrainTestSetEvaluator
-annotation <adams.core.base.BaseAnnotation> (property: annotations) The annotations to attach to this actor. default:
-skip <boolean> (property: skip) If set to true, transformation is skipped and the input token is just forwarded as it is. default: false
-stop-flow-on-error <boolean> (property: stopFlowOnError) If set to true, the flow execution at this level gets stopped in case this actor encounters an error; the error gets propagated; useful for critical actors. default: false min-user-mode: Expert
-silent <boolean> (property: silent) If enabled, then no errors are output in the console; Note: the enclosing actor handler must have this enabled as well. default: false min-user-mode: Expert
-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
-always-use-container <boolean> (property: alwaysUseContainer) If enabled, always outputs an evaluation container. default: false
-classifier <adams.flow.core.CallableActorReference> (property: classifier) The callable classifier actor to train and evaluate on the test data. default: WekaClassifierSetup
-no-predictions <boolean> (property: discardPredictions) If enabled, the collection of predictions during evaluation is suppressed, wich will conserve memory. default: false
-prefer-jobrunner <boolean> (property: preferJobRunner) If enabled, tries to offload the processing onto a adams.flow.standalone.JobRunnerInstance. default: false
