Constructor Detail

HyperplaneInstance

public HyperplaneInstance(Hyperplane hyperplane,
                          java.lang.String subpopulationId,
                          java.lang.Object source)

Method Detail

toGUI

public Viewer toGUI()

Description copied from interface: Visible

Create a view of this object

Specified by:

toGUI in interface Visible

getWeight

public double getWeight(Feature f)

Description copied from interface: Instance

Get the weight assigned to a feature in this instance.

Specified by:

getWeight in interface Instance

binaryFeatureIterator

public java.util.Iterator<Feature> binaryFeatureIterator()

Description copied from interface: Instance

Return an iterator over all binary features.

Specified by:

binaryFeatureIterator in interface Instance

numericFeatureIterator

public java.util.Iterator<Feature> numericFeatureIterator()

Description copied from interface: Instance

Return an iterator over all numeric features.

Specified by:

numericFeatureIterator in interface Instance

featureIterator

public java.util.Iterator<Feature> featureIterator()

Description copied from interface: Instance

Return an iterator over all features

Specified by:

featureIterator in interface Instance

numFeatures

public int numFeatures()

Description copied from interface: Instance

Return the number of all the features

Specified by:

numFeatures in interface Instance

getWeight

public double getWeight()

getSource

public java.lang.Object getSource()

Description copied from interface: Instance

Get the underlying object used that this instance describes

Specified by:

getSource in interface Instance

getSubpopulationId

public java.lang.String getSubpopulationId()

Description copied from interface: Instance

Get the subpopulation from which this instance was drawn. A null id is considered to be a unique subpopulation---different from every other subpopulation, including other nulls. A subpopulation is a subset of the training data which is expected to contain additional regularities - for instance, pages from the same site, or spans from the same document. Testing routines may use subpopulation's to more correctly spit datasets into train/test subsets.
