Class CentroidObservationInteger

java.lang.Object
  be.ac.ulg.montefiore.run.jahmm.CentroidObservationInteger

All Implemented Interfaces:

Centroid<ObservationInteger>

public class CentroidObservationInteger
extends java.lang.Object
implements Centroid<ObservationInteger>

This class represents the centroid of a set of ObservationInteger.

Constructor Summary

CentroidObservationInteger(ObservationInteger o)

Method Summary

double	distance(ObservationInteger e) Returns the distance from this centroid to a given element.
void	reevaluateAdd(ObservationInteger e, java.util.List<? extends ObservationInteger> v) Reevalue the value of this centroid, knowing that it currently is the centroid of the observations composing v and that we want it to be the centroid of v plus the value of the observation e.
void	reevaluateRemove(ObservationInteger e, java.util.List<? extends ObservationInteger> v) Reevalue the value of this centroid, knowing that it currently is the centroid of the observations composing v and that we want it to be the centroid of v minus the value of the observation e.

Method Detail

reevaluateAdd

public void reevaluateAdd(ObservationInteger e,
                          java.util.List<? extends ObservationInteger> v)

Description copied from interface: Centroid

Reevalue the value of this centroid, knowing that it currently is the centroid of the observations composing v and that we want it to be the centroid of v plus the value of the observation e.

Specified by:

reevaluateAdd in interface Centroid<ObservationInteger>

Parameters:

e - An observation that must be involved in the computation of the new value of this centroid.

v - The set of observations that gave the current value of this centroid.

reevaluateRemove

public void reevaluateRemove(ObservationInteger e,
                             java.util.List<? extends ObservationInteger> v)

Description copied from interface: Centroid

Reevalue the value of this centroid, knowing that it currently is the centroid of the observations composing v and that we want it to be the centroid of v minus the value of the observation e.

Specified by:

reevaluateRemove in interface Centroid<ObservationInteger>

Parameters:

e - An observation that must not be involved in the computation of the new value of this centroid.

v - The set of observations (which holds o) that gave the current value of this centroid.

distance

public double distance(ObservationInteger e)

Returns the distance from this centroid to a given element. This distance is the absolute value of the difference between the value of this centroid and the value of the argument.

Specified by:

distance in interface Centroid<ObservationInteger>

Parameters:

e - The element, which must be an ObservationInteger.

Returns:

The distance to the centroid.
