IteratedSingleClassifierEnhancer

public IteratedSingleClassifierEnhancer()
Method Detail

buildClassifier

public void buildClassifier(Instances data)
                     throws java.lang.Exception
Stump method for building the classifiers.

Specified by:
buildClassifier in class Classifier
Parameters:
data - the training data to be used for generating the bagged classifier.
Throws:
java.lang.Exception - if the classifier could not be built successfully

listOptions

public java.util.Enumeration listOptions()
Returns an enumeration describing the available options.

Specified by:
listOptions in interface OptionHandler
Overrides:
listOptions in class SingleClassifierEnhancer
Returns:
an enumeration of all the available options.

setOptions

public void setOptions(java.lang.String[] options)
                throws java.lang.Exception
Parses a given list of options. Valid options are:

-W classname
Specify the full class name of the base learner.

-I num
Set the number of iterations (default 10).

Options after -- are passed to the designated classifier.

Specified by:
setOptions in interface OptionHandler
Overrides:
setOptions in class SingleClassifierEnhancer
Parameters:
options - the list of options as an array of strings
Throws:
java.lang.Exception - if an option is not supported

getOptions

public java.lang.String[] getOptions()
Gets the current settings of the classifier.

Specified by:
getOptions in interface OptionHandler
Overrides:
getOptions in class SingleClassifierEnhancer
Returns:
an array of strings suitable for passing to setOptions

numIterationsTipText

public java.lang.String numIterationsTipText()
Returns the tip text for this property

Returns:
tip text for this property suitable for displaying in the explorer/experimenter gui

setNumIterations

public void setNumIterations(int numIterations)
Sets the number of bagging iterations


getNumIterations

public int getNumIterations()
Gets the number of bagging iterations

Returns:
the maximum number of bagging iterations
