Field Detail

meanVarianceMap

private java.util.Map<java.lang.String,ZTransformationModel.MeanVariance> meanVarianceMap

This map contains all information about the mean and variance values for all attributes. Maps attribute names to MeanVariance objects.

Constructor Detail

ZTransformationModel

public ZTransformationModel()

Creates a new model. Necessary for construction via reflection.

Method Detail

addMeanVariance

public void addMeanVariance(java.lang.String name,
                            double mean,
                            double variance)

Adds the mean and variance information for an attribute with the given name.

apply

public void apply(ExampleSet exampleSet)
           throws OperatorException

Performs the transformation.

Throws:

OperatorException

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

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
