Method Detail

fit

public final void fit(cern.colt.matrix.DoubleMatrix2D x,
                      double[] y)

Description copied from interface: IClassifier

Trains this classifier using the supplied data.

Specified by:

fit in interface IClassifier

Parameters:

x - the attributes of the instances.

y - the targets of the instances.

isTrained

public final boolean isTrained()

Description copied from interface: IClassifierInformation

Returns whether this classifier has been trained.

Specified by:

isTrained in interface IClassifierInformation

Returns:

Returns true if the classifier has been trained or false otherwise.

getAttributeCount

public final int getAttributeCount()

Description copied from interface: IClassifierInformation

Returns the number of attributes the classifier has been trained on.

Specified by:

getAttributeCount in interface IClassifierInformation

Returns:

Returns the number of attributes the classifier has been trained on or -1 if the classifier has not been trained.

getLabels

public final java.lang.Double[] getLabels()

Description copied from interface: IClassifierInformation

Returns the set of class labels the classifier has been trained on.

Specified by:

getLabels in interface IClassifierInformation

Returns:

Returns the class labels the classifier has been trained on in increasing order (the index is the class id) or null if the classifier has not been trained.

internalFit

protected abstract void internalFit(cern.colt.matrix.DoubleMatrix2D x,
                                    double[] y)
