trainableSegmentation

Class ReusableDenseInstance

java.lang.Object

weka.core.AbstractInstance

weka.core.DenseInstance

trainableSegmentation.ReusableDenseInstance

All Implemented Interfaces:

Serializable, weka.core.Copyable, weka.core.Instance, weka.core.RevisionHandler

public class ReusableDenseInstance
extends weka.core.DenseInstance

This class extends the WEKA DenseInstance so it can be reused. This is an important feature to save time and memory when classifying iteratively many new instances.
