Name

adams.flow.transformer.WekaInstancesHistogramRanges

Synopsis

Outputs the ranges generated by adams.data.statistics.ArrayHistogram using the incoming weka.core.Instances object.
The actor just uses the internal format (double array) and does not check whether the attributes are actually numeric.

Additional information

Flow input/output:
- input: weka.core.Instances
- output: java.lang.String

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	WekaInstancesHistogramRanges

  
  
• 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 ranges are output as array rather than one by one.

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

  
  
• dataType
  

  Whether to retrieve rows or columns from the Instances object.

  command-line	-type <ROW_BY_INDEX|COLUMN_BY_INDEX|COLUMN_BY_REGEXP>
  default	COLUMN_BY_INDEX

  
  
• locations
  

  The locations of the data, depending on the chosen data type that can be either indices, attribute names or regular expressions on the attribute names.

  command-line	-location <adams.core.base.BaseString> [-location ...]
  default

  
  
• binCalculation
  

  Defines how the number of bins are calculated.

  command-line	-bin-calc <MANUAL|FREQUENCY|DENSITY|STURGES|SCOTT|SQRT>
  default	MANUAL

  
  
• numBins
  

  The number of bins to use in case of manual bin calculation.

  command-line	-num-bins <int>
  default	50
  minimum	1

  
  
• binWidth
  

  The bin width to use for some of the calculations.

  command-line	-bin-width <double>
  default	1.0
  minimum	1.0E-5

  
  
• normalize
  

  If set to true the data gets normalized first before the histogram is calculated.

  command-line	-normalize <boolean>
  default	false

  
  
• useFixedMinMax
  

  If enabled, then the user-specified min/max values are used for the bin calculation rather than the min/max from the data (allows comparison of histograms when generating histograms over a range of arrays).

  command-line	-use-fixed-min-max <boolean>
  default	false

  
  
• manualMin
  

  The minimum to use when using manual binning with user-supplied min/max enabled.

  command-line	-manual-min <double>
  default	0.0

  
  
• manualMax
  

  The maximum to use when using manual binning with user-supplied max/max enabled.

  command-line	-manual-max <double>
  default	1.0

  
  
• numDecimals
  

  The number of decimals to show in the bin descriptions.

  command-line	-num-decimals <int>
  default	3
  minimum	0
