Constructor Detail

ProportionNormalizationModel

public ProportionNormalizationModel(ExampleSet exampleSet,
                                    java.util.HashMap<java.lang.String,java.lang.Double> attributeSums)

Create a new normalization model.

Method Detail

applyOnData

public ExampleSet applyOnData(ExampleSet exampleSet)
                       throws OperatorException

Performs the transformation.

Specified by:

applyOnData in class PreprocessingModel

Throws:

OperatorException

getName

public java.lang.String getName()

Returns a nicer name. Necessary since this model is defined as inner class.

Specified by:

getName in interface ResultObject

Overrides:

getName in class AbstractModel

toString

public java.lang.String toString()

Returns a string representation of this model.

Specified by:

toString in interface Readable

Overrides:

toString in class java.lang.Object

getTargetAttributes

public Attributes getTargetAttributes(ExampleSet viewParent)

Description copied from interface: ViewModel

This method has to return a legal Attributes object containing every Attribute, the view should contain

Returns:

The attribute object

getValue

public double getValue(Attribute targetAttribute,
                       double value)

Description copied from interface: ViewModel

This method has to provide the attribute value mapping for the view. The views attributes will ask this method for their value.

Parameters:

targetAttribute - the attribute, which asks for his value

value - the value the source attribute had in original data

Returns:

the value the attribute should have in target view
