java.lang.Objectedu.udo.cs.yale.operator.Operator
edu.udo.cs.yale.operator.features.AttributeWeightsApplier
public class AttributeWeightsApplier
This operator deselects attributes with a weight value of 0.0. The values of
the other numeric attributes will be recalculated based on the
WeightApplier
and the weights delivered as AttributeWeights
object in the input. This operator could not be used to select a subset of
features which was determined by a former selection scheme. For this purpose
the operator
AttributeWeightSelection
should be used.

Operator
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.

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).
