Class DiscretizationScheme

java.lang.Object
  org.knime.base.node.preproc.discretization.caim2.DiscretizationScheme

public class DiscretizationScheme
extends Object

Represents a discretization scheme. Therefore, an ordered set of boundaries is hold.

Author:

Christoph Sieb, University of Konstanz

Constructor Summary

DiscretizationScheme(Config content)
Creates a DiscretizationScheme from a Config object.

DiscretizationScheme(DiscretizationScheme dScheme)
Creates a discretization scheme from a given one.

DiscretizationScheme(Interval initialInterval)
Creates a discretization scheme from an initial interval.

Method Summary

double[]	getBounds() Returns the bounds of the intervals.
String	getDiscreteValue(double value) Determins the interval of the value and returns a discrete value for that.
int	getIntervalIndexOf(double value) Returns the index of the interval the given value is contained in.
int	getNumIntervals()
void	insertBound(double newBound) Inserts a new bound into an interval.
void	saveToModelContent(Config modelContent) Saves this scheme to a ModelContentWO object.
String	toString()

Constructor Detail

DiscretizationScheme

public DiscretizationScheme(Interval initialInterval)

Creates a discretization scheme from an initial interval.

Parameters:

initialInterval - the initial interval

DiscretizationScheme

public DiscretizationScheme(DiscretizationScheme dScheme)

Creates a discretization scheme from a given one. Creates a deep copy except the intervals which are imutable.

Parameters:

dScheme - the discretization scheme to copy

DiscretizationScheme

public DiscretizationScheme(Config content)
                     throws InvalidSettingsException

Creates a DiscretizationScheme from a Config object.

Parameters:

content - the content object to restore the model from

Throws:

InvalidSettingsException - thrown if the settings are invalid

Method Detail

getIntervalIndexOf

public int getIntervalIndexOf(double value)

Returns the index of the interval the given value is contained in.

Parameters:

value - the value to find the interval index for

Returns:

the index of the interval the value is contained in; -1 if not contained in any interval

getDiscreteValue

public String getDiscreteValue(double value)

Determins the interval of the value and returns a discrete value for that.

Parameters:

value - the value to discretize

Returns:

the discretized value

insertBound

public void insertBound(double newBound)

Inserts a new bound into an interval. This results in one additional interval. The new bound must be located within an interval.

Parameters:

newBound - the new bound to insert

getNumIntervals

public int getNumIntervals()

Returns:

the number of intervals of this discretization scheme

toString

public String toString()

Overrides:

toString in class Object

saveToModelContent

public void saveToModelContent(Config modelContent)

Saves this scheme to a ModelContentWO object.

Parameters:

modelContent - the Config object to store the DiscretizationScheme to

getBounds

public double[] getBounds()

Returns the bounds of the intervals. It is assumed that the bounderies are touching each other.

Returns:

the boundary values
