public class WekaCrossValidationClustererEvaluator extends AbstractCallableWekaClustererEvaluator implements adams.core.Randomizable
Cross-validates a clusterer on an incoming dataset. The clusterer setup being used in the evaluation is a callable 'Clusterer' actor.
Input/output:
- accepts:
weka.core.Instances
- generates:
adams.flow.container.WekaClusterEvaluationContainer
Container information:
- adams.flow.container.WekaClusterEvaluationContainer: Evaluation, Model, Log-likelohood
-logging-level <OFF|SEVERE|WARNING|INFO|CONFIG|FINE|FINER|FINEST> (property: loggingLevel) The logging level for outputting errors and debugging output. default: WARNING
-name <java.lang.String> (property: name) The name of the actor. default: WekaCrossValidationClustererEvaluator
-annotation <adams.core.base.BaseText> (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 gets stopped in case this actor encounters an error; useful for critical actors. default: false
-clusterer <adams.flow.core.CallableActorReference> (property: clusterer) The callable clusterer actor to cross-validate on the input data. default: WekaClustererSetup
-seed <long> (property: seed) The seed value for the cross-validation (used for randomization). default: 1
-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
