Name

adams.flow.transformer.WekaSpreadSheetToPredictions

Synopsis

Turns the predictions stored in the incoming spreadsheet (actual and predicted) into a Weka weka.classifiers.Evaluation object.
For recreating the predictions of a nominal class, the class distributions must be present in the spreadsheet as well.

Additional information

Flow input/output:
- input: adams.data.spreadsheet.SpreadSheet
- output: weka.classifiers.Evaluation

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	WekaSpreadSheetToPredictions

  
  
• 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

  
  
• actual
  

  The column with the actual values.

  command-line	-actual <adams.data.spreadsheet.SpreadSheetColumnIndex>
  default	Actual
  example	An index is a number starting with 1; column names (case-sensitive) as well as the following placeholders can be used: first, second, third, last_2, last_1, last; numeric indices can be enforced by preceding them with '#' (eg '#12'); column names can be surrounded by double quotes.

  
  
• predicted
  

  The column with the predicted values.

  command-line	-predicted <adams.data.spreadsheet.SpreadSheetColumnIndex>
  default	Predicted
  example	An index is a number starting with 1; column names (case-sensitive) as well as the following placeholders can be used: first, second, third, last_2, last_1, last; numeric indices can be enforced by preceding them with '#' (eg '#12'); column names can be surrounded by double quotes.

  
  
• classDistribution
  

  The columns containing the class distribution (nominal class).

  command-line	-class-distribution <adams.data.spreadsheet.SpreadSheetUnorderedColumnRange>
  default
  example	A range is a comma-separated list of single 1-based indices or sub-ranges of indices ('start-end'); column names (case-sensitive) as well as the following placeholders can be used: first, second, third, last_2, last_1, last; numeric indices can be enforced by preceding them with '#' (eg '#12'); column names can be surrounded by double quotes.

  
  
• useColumnNamesAsClassLabels
  

  If enabled, the names of the class distribution columns are used as labels in the fake evaluation; automatically removes the surrounding 'Distribution (...)'.

  command-line	-column-names-as-class-labels <boolean>
  default	false

  
  
• weight
  

  The (optional) column with the weights of the instances; 1.0 is assumed by default.

  command-line	-weight <adams.data.spreadsheet.SpreadSheetColumnIndex>
  default
  example	An index is a number starting with 1; column names (case-sensitive) as well as the following placeholders can be used: first, second, third, last_2, last_1, last; numeric indices can be enforced by preceding them with '#' (eg '#12'); column names can be surrounded by double quotes.

  
  
• sortLabels
  

  If enabled, the labels get sorted with the specified comparator.

  command-line	-sort-labels <boolean>
