Class ThresholdApplier

java.lang.Object
  extended by edu.udo.cs.yale.operator.Operator
      extended by edu.udo.cs.yale.operator.postprocessing.ThresholdApplier
All Implemented Interfaces:
ConfigurationListener

public class ThresholdApplier
extends Operator

This operator applies the given threshold to an example set and maps a soft prediction to crisp values. If the confidence for the second class (usually positive for YALE) is greater than the given threshold the prediction is set to this class.

Method Detail

apply

public IOObject[] apply()
                 throws OperatorException
Description copied from class: Operator
Implement this method in subclasses.

Specified by:
apply in class Operator
Throws:
OperatorException


getInputClasses

public java.lang.Class[] getInputClasses()
Description copied from class: Operator
Returns the classes that are needed as input. May be null or an empty (no desired input). As default, all delivered input objects are consumed and must be also delivered as output in both Operator.getOutputClasses() and Operator.apply() if this is necessary. This default behavior can be changed by overriding Operator.getInputDescription(Class). Subclasses which implement this method should not make use of parameters since this method is invoked by getParameterTypes(). Therefore, parameters are not fully available at this point of time and this might lead to exceptions. Please use InputDescriptions instead.

Specified by:
getInputClasses in class Operator


getOutputClasses

public java.lang.Class[] getOutputClasses()
Description copied from class: Operator
Returns the classes that are guaranteed to be returned by apply() as additional output. Please note that input object which should not be consumed must also be defined by this method (e.g. for preprocessing operators). The default behavior for input consumation is defined by Operator.getInputDescription(Class) and can be changed by overwriting this method. Objects which are not consumed must not be defined as additional output in this method. May be null or an empy array (no additional output is produced).
