public class FastICA
extends Operator

This operator performs the independent componente analysis (ICA). Implementation of the FastICA-algorithm of Hyvaerinen und Oja. The operator outputs a FastICAModel. With the ModelApplier you can transform the features.

Method Detail

doWork

public void doWork()
            throws OperatorException

Description copied from class: Operator

Performs the actual work of the operator and must be implemented by subclasses. Replaces the old method apply().

Overrides:

doWork in class Operator

Throws:

OperatorException

getParameterTypes

public java.util.List<ParameterType> getParameterTypes()

Description copied from class: Operator

Returns a list of ParameterTypes describing the parameters of this operator. The default implementation returns an empty list if no input objects can be retained and special parameters for those input objects which can be prevented from being consumed. ATTENTION! This will create new parameterTypes. For calling already existing parameter types use getParameters().getParameterTypes();

Specified by:

getParameterTypes in interface ParameterHandler

Overrides:

getParameterTypes in class Operator
