All Implemented Interfaces:

ComponentWeightsCreatable, IOObject, Model, ResultObject, Saveable

public class FastICAModel
extends IOModel
implements ComponentWeightsCreatable

This is the transformation model of the FastICA. The number of independent components is initially specified by the FastICA. Additionally you can specify parameters in the ModelApplier.

• keep_attributes true|false If true, the original features are not removed.

Method Detail

apply

public void apply(ExampleSet testSet)
           throws OperatorException

Description copied from interface: Model

Applies the model on the given example set.

Specified by:

apply in interface Model

Throws:

OperatorException

readData

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

Description copied from class: IOModel

Reads the model data from the stream.

Specified by:

readData in class IOModel

Throws:

java.io.IOException

writeData

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

Description copied from class: AbstractModel

Writes the model to a stream.

Specified by:

writeData in class AbstractModel

Throws:

java.io.IOException

setParameter

public void setParameter(java.lang.String name,
