Class HyperPipes.HyperPipe

java.lang.Object
  weka.classifiers.misc.HyperPipes.HyperPipe

All Implemented Interfaces:

java.io.Serializable

Enclosing class:

HyperPipes

class HyperPipes.HyperPipe

extends java.lang.Object

implements java.io.Serializable

Represents an n-dimensional structure that bounds all instances passed to it (generally all of a given class value).

Field Summary

protected boolean[][]	m_NominalBounds Contains the nominal bounds of all instances in the HyperPipe
protected double[][]	m_NumericBounds Contains the numeric bounds of all instances in the HyperPipe

Constructor Summary

HyperPipes.HyperPipe(Instances instances)
Creates the HyperPipe as the n-dimensional parallel-piped with minimum volume containing all the points in pointSet.

Method Summary

void	addInstance(Instance instance) Updates the bounds arrays with a single instance.
double	partialContains(Instance instance) Returns the fraction of the dimensions of a given instance with values lying within the corresponding bounds of the HyperPipe.

Constructor Detail

HyperPipes.HyperPipe

public HyperPipes.HyperPipe(Instances instances)
                     throws java.lang.Exception

Creates the HyperPipe as the n-dimensional parallel-piped with minimum volume containing all the points in pointSet.

Parameters:

instances - all instances belonging to the same class

Throws:

java.lang.Exception - if missing values are found

Method Detail

addInstance

public void addInstance(Instance instance)
                 throws java.lang.Exception

Updates the bounds arrays with a single instance. Missing values are ignored (i.e. they don't change the bounds for that attribute)

Parameters:

instance - the instance

Throws:

java.lang.Exception - if any missing values are encountered

partialContains

public double partialContains(Instance instance)
                       throws java.lang.Exception

Returns the fraction of the dimensions of a given instance with values lying within the corresponding bounds of the HyperPipe.

Parameters:

instance - the instance

Throws:

java.lang.Exception - if any missing values are encountered
