Class DerivativeSettings

java.lang.Object

com.bayesia.api.discretization.settings.DerivativeSettings

All Implemented Interfaces:

DiscretizationSettings

public class DerivativeSettings
extends java.lang.Object
implements DiscretizationSettings

This class is used to perform discretization using the derivative discretization algorithm. This algorithm analyses the data to find where the derivate of the curve is changing its sign. Once done, the smallest intervals are discarded in order to obtain the required number of intervals. It must be used with APIUtils.discretize(DiscretizationSettings, double[], double[])

Constructor Detail

DerivativeSettings

public DerivativeSettings(int intervalCount,
                          boolean logUsed)

Create settings for the derivative discretization algorithm providing the number of intervals we want to obtain. This number must be superior or equal to 2. In some cases of data distribution, it is possible to use the log10 of the data before performing discretization by specifying logUsed

Parameters:

intervalCount - the number of intervals

logUsed - indicates if the data have to be converted into log before discretization

Method Detail

getDiscretization

public APIUtils.DISCRETIZATION getDiscretization()

Description copied from interface: DiscretizationSettings

Return a DISCRETIZATION indicating the discretization algorithm to use

Specified by:

getDiscretization in interface DiscretizationSettings

Returns:

the discretization to use

getIntervalCount

public int getIntervalCount()

Returns:

the number of intervals

isLogUsed

public boolean isLogUsed()

Returns:

true if the data have to be converted as log before discretization, false otherwise
