public class ProjectCoordinate

extends Projector

Project Coordinate is perhaps the simplest possible projection algorithm; It simply takes two specificed dimensions in the high dimensional space, and uses these as the basis for the low-dimensional space. In effect it just takes a 2-dimensional subspace of the high-dimensional space.

Method Detail

init

public void init(Dataset up,
                 Dataset down)

Description copied from class: Projector

Initialize the projector with high and low-d data

Overrides:

init in class Projector

Parameters:

up - Reference to high dimensional dataset

down - Reference to low dimensional dataset. Pass NULL if not available

project

public void project()

Description copied from class: Projector

Perform operations necessay to project the data. For iterable functions this is just a stub.

Specified by:

project in class Projector

checkCoordinates

public void checkCoordinates()

If the current coordinate axes are outside acceptable bounds, set them to acceptable values (currently 0 and 1).

isExtendible

public boolean isExtendible()

Specified by:

isExtendible in class Projector

Returns:

true if this projection algorithm accepts new new points, false otherwise

isIterable

public boolean isIterable()

Specified by:

isIterable in class Projector

Returns:

true if this projection algorithm is iterable, false otherwise

iterate

public double iterate()

Description copied from class: Projector

Iterate, if it is iterable. For non iterable-projectors this is just a stub

Specified by:

iterate in class Projector

Returns:

the current error

getHi_d1

public int getHi_d1()

Returns:

the first coordinate projected onto

getHi_d2

public int getHi_d2()

Returns:

the second coordinate projected onto

setHi_d1

public void setHi_d1(int i)

Parameters:

i - the first coordinate to project onto

setHi_d2

public void setHi_d2(int i)

Parameters:

i - the second coordinate to project onto

isAutoFind

public boolean isAutoFind()

In auto-find the projection automatically uses the most variant dimensions

Returns:

true if in auto-find mode, false otherwise

setAutoFind

public void setAutoFind(boolean b)

In auto-find the projection automatically uses the most variant dimensions

Parameters:

b - whether to use auto-find mode
