Name

adams.flow.transformer.MekaClassSelector

Synopsis

Determines which attributes to use as class attributes using either a regular expression or an attribute index range.
In case the attribute range is a non-empty string, this will take precedence over the regular expression.
Anything that follows a ':' or ' ' (blank) gets removed from the original relation name in order to create a valid MEKA one.

Additional information

Flow input/output:
- input: weka.core.Instances
- output: weka.core.Instances

Options

• loggingLevel
  

  The logging level for outputting errors and debugging output.

  command-line	-logging-level <OFF|SEVERE|WARNING|INFO|CONFIG|FINE|FINER|FINEST>

• name
  

  The name of the actor.

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

• 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.

  default	false
  min-user-mode	Expert

  
  
• range
  

  The attribute range.

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

  
  
• regex
  

  The regular expression used for selecting the class attributes (matched against the attribute names).

  command-line	-regex <adams.core.base.BaseRegExp>
  default	.*
