Name

adams.flow.transformer.WekaRandomSplit

Synopsis

Splits a dataset into a training and test set according to a specified split percentage. Randomization can be suppressed using the 'preserve order' option.
The training set can be accessed in the container with 'Train' and the test set with 'Test'.
Depending on the split generator in use, more than one container may be output.

Additional information

- input: weka.core.Instances
- output: adams.flow.container.WekaTrainTestSetContainer

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	WekaRandomSplit

  
  
• 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

  
  
• outputArray
  

  If enabled, the splits are output as array rather than one-by-one.

  command-line	-output-array <boolean>
  default	false

  
  
• preserveOrder
  

  If set to true, then the order is preserved by suppressing randomization; overrides the value defined by the split generator scheme.

  command-line	-preserve-order <boolean>
  default	false

  
  
• seed
  

  The seed value for the randomization; overrides the value defined by the split generator scheme.

  command-line	-seed <long>
  default	1

  
  
• percentage
  

  The percentage for the split (between 0 and 1); overrides the value defined by the split generator scheme.

  command-line	-percentage <double>
  default	0.66
  minimum	1.0E-4
  maximum	0.9999

  
  
• createView
  

  If enabled, views of the dataset are created instead of actual copies; overrides the value defined by the split generator scheme.

  command-line	-create-view <boolean>
  default	false

  
  
• generator
  

  The scheme to use for generating the split; the actor options take precedence over the scheme's ones.

  command-line	-generator <weka.classifiers.RandomSplitGenerator>
  default	weka.classifiers.DefaultRandomSplitGenerator
