All Implemented Interfaces:

ConfigurationListener

public class FunctionValueSeries
extends Operator

Calculates for each sample a series of function values. Therefor the weights of the JMySVMModel are ordered descending by their absolute value. The x-th value of the series is the function valueof the example by taking the first x weights. The other weights are to zero. So the series attribute count values. Additionally the user can enter nr_attributes which are summerized to one value calculation. This can reduces the number of calculations dramatically. The result is an ExampleSet containing for each example a series of function values given by the attribute values.

Method Detail

apply

public IOObject[] apply()
                 throws OperatorException

Description copied from class: Operator

Implement this method in subclasses.

Specified by:

apply in class Operator

Throws:

OperatorException

orderWeights

public void orderWeights(double[] array,
                         int links,
                         int rechts)

Order the subarry from index anfang to index ende with QuickSort Also the attribute_index is ordered.

Parameters:

array -

links -

rechts -

orderWeights

public void orderWeights(double[] weights)

Order weights with QuickSort. Performs an ordering to the absolute value

getInputClasses

public java.lang.Class[] getInputClasses()

Description copied from class: Operator

Returns the classes that are needed as input. May be null or an empty (no desired input). As default, all delivered input objects are consumed and must be also delivered as output in both Operator.getOutputClasses() and Operator.apply() if this is necessary. This default behavior can be changed by overriding Operator.getInputDescription(Class). Subclasses which implement this method should not make use of parameters since this method is invoked by getParameterTypes(). Therefore, parameters are not fully available at this point of time and this might lead to exceptions. Please use InputDescriptions instead.

Specified by:

getInputClasses in class Operator

getOutputClasses

public java.lang.Class[] getOutputClasses()

Description copied from class: Operator

Returns the classes that are guaranteed to be returned by apply() as additional output. Please note that input object which should not be consumed must also be defined by this method (e.g. for preprocessing operators). The default behavior for input consumation is defined by Operator.getInputDescription(Class) and can be changed by overwriting this method. Objects which are not consumed must not be defined as additional output in this method. May be null or an empy array (no additional output is produced).

Specified by:

getOutputClasses in class Operator

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.

Overrides:

getParameterTypes in class Operator
