adams.flow.transformer.WekaCrossValidationClustererEvaluator

Synopsis

Cross-validates a clusterer on an incoming dataset. The clusterer setup being used in the evaluation is a callable 'Clusterer' actor.

Additional information

Flow input/output:
- input: weka.core.Instances
- output: adams.flow.container.WekaClusterEvaluationContainer

Container information:

Options

• loggingLevel
  

  The logging level for outputting errors and debugging output.

  command-line	-logging-level <OFF|SEVERE|WARNING|INFO|CONFIG|FINE|FINER|FINEST>
  default	WARNING
  min-user-mode	Expert

  
  
• name
  

  The name of the actor.

  command-line	-name <java.lang.String>
  default	WekaCrossValidationClustererEvaluator

  
  
• annotations
  

  The annotations to attach to this actor.

  command-line	-annotation <adams.core.base.BaseAnnotation>
  default

  
  
• skip
  

  If set to true, transformation is skipped and the input token is just forwarded as it is.

  command-line	-skip <boolean>
  default	false

  
  
• 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.

  command-line	-stop-flow-on-error <boolean>
  default	false
  min-user-mode	Expert

  
  
• silent
  

  If enabled, then no errors are output in the console; Note: the enclosing actor handler must have this enabled as well.

  command-line	-silent <boolean>
  default	false
  min-user-mode	Expert

  
  
• clusterer
  

  The callable clusterer actor to cross-validate on the input data.

  command-line	-clusterer <adams.flow.core.CallableActorReference>
  default	WekaClustererSetup

  
  
• seed
  

  The seed value for the cross-validation (used for randomization).

  command-line	-seed <long>
  default	1

  
  
• folds
  

  The number of folds to use in the cross-validation; use -1 for leave-one-out cross-validation (LOOCV).

  command-line	-folds <int>
  default	10
  minimum	-1
