Class SupportVectorCounter

java.lang.Object
  extended by com.rapidminer.operator.Operator
      extended by com.rapidminer.operator.performance.SupportVectorCounter
All Implemented Interfaces:
ConfigurationListener, PreviewListener, ParameterHandler, LoggingHandler

public class SupportVectorCounter
extends Operator

Returns a performance vector just counting the number of support vectors of a given support vector based model (kernel model). Please note that this operator will try to derive the number of support vectors of the first delivered model and might fail on this task if no appropriate kernel based model is delivered. Currently, at least the models delivered by the operator JMySVM, MyKLR, LibSVM, GPLearner, KernelLogisticRegression, RVM, and the EvoSVM should be supported.

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

getInputDescription

public InputDescription getInputDescription(java.lang.Class cls)
Shows a parameter keep_example_set with default value "false".

Overrides:
getInputDescription in class Operator

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 objects which should not be consumed must also be defined by this method (e.g. an example set which is changed but not consumed in the case of a preprocessing operator must be defined in both, the methods Operator.getInputClasses() and Operator.getOutputClasses()). 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 (defined by changing the implementation in Operator.getInputDescription(Class)) must not be defined as additional output in this method.

May deliver null or an empy array (no additional output is produced or guaranteed). Must return the class array of delivered output objects otherwise.

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.

Specified by:
getParameterTypes in interface ParameterHandler
Overrides:
getParameterTypes in class Operator
