Class LinearThresholdUnit.Parameters

java.lang.Object
  LBJ2.learn.Parameters
      LBJ2.learn.LinearThresholdUnit.Parameters

Direct Known Subclasses:

SparsePerceptron.Parameters, SparseWinnow.Parameters

Enclosing class:

LinearThresholdUnit

public static class LinearThresholdUnit.Parameters
extends Parameters

Simply a container for all of LinearThresholdUnit's configurable parameters. Using instances of this class should make code more readable and constructors less complicated.

Field Summary

double	initialWeight The weight associated with a feature when first added to the vector; default LinearThresholdUnit.defaultInitialWeight.
double	negativeThickness The thickness of the hyperplane on the negative side; default 0.
double	positiveThickness The thickness of the hyperplane on the positive side; default 0.
double	thickness This thickness will be added to both positiveThickness and negativeThickness; default LinearThresholdUnit.defaultThickness.
double	threshold The score is compared against this value to make predictions; default LinearThresholdUnit.defaultThreshold.
SparseWeightVector	weightVector The LTU's weight vector; default is an empty vector.

Constructor Summary

LinearThresholdUnit.Parameters()
Sets all the default values.
