Method Detail

getCoverage

public double getCoverage()

Returns:

Coverage of the class description.

getAddition

public double getAddition()

Let C be the considered class description and A the class to learn. The addition number is calculated as the number of instances of C which are also instances of A divided by the number of instances of C.

Returns:

Additional instances of the class description.

getAccuracy

public double getAccuracy()

Description copied from class: Score

This method returns a value, which indicates how accurate a class description solves a learning problem.

Specified by:

getAccuracy in class Score

Returns:

A value between 0 and 1 indicating the quality (of a class description).

getCoveredInstances

public Set<Individual> getCoveredInstances()

Returns:

the coveredInstances

getNotCoveredInstances

public Set<Individual> getNotCoveredInstances()

Returns:

getAdditionalInstances

public Set<Individual> getAdditionalInstances()

Returns:

the additionalInstances

setConsistent

public void setConsistent(boolean isConsistent)

setFollowsFromKB

public void setFollowsFromKB(boolean followsFromKB)

isConsistent

public boolean isConsistent()

Returns:

the isConsistent

followsFromKB

public boolean followsFromKB()

Returns:
