getModifiedLengthScore

public abstract ScorePosNeg getModifiedLengthScore(int newLength)

The score of a concept depends on how good it classifies the examples of a learning problem and the length of the concept itself. If a given concept is known to have equal classification properties than the concept this score object is based on, then this method can be used to calculate its score value by using the length of this concept as parameter.

Parameters:

newLength - Length of the concept.

Returns:

Score.
