Field Detail

min

private double min

The minimum value for each attribute after normalization.

max

private double max

The maximum value for each attribute after normalization.

Constructor Detail

MinMaxNormalizationModel

public MinMaxNormalizationModel()

Create a new model. Necessary for construction via reflection.

MinMaxNormalizationModel

public MinMaxNormalizationModel(double min,
                                double max)

Create a new normalization model.

Method Detail

apply

public void apply(ExampleSet exampleSet)
           throws OperatorException

Performs the transformation.

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 ResultObjectAdapter

toString

public java.lang.String toString()

Returns a string representation of this model.

Overrides:

toString in class java.lang.Object

writeData

public void writeData(java.io.ObjectOutputStream out)
               throws java.io.IOException

Writes the model data into the given stream.

Specified by:

writeData in class AbstractModel

Throws:

java.io.IOException

readData

public void readData(java.io.ObjectInputStream in)
              throws java.io.IOException

Reads the model data from the given stream.

Specified by:

readData in class IOModel

Throws:

java.io.IOException
