medusa.georgios.enhanced_mcl.AbstractSimilarity

All Implemented Interfaces:

java.io.Serializable, DistanceMeasure

public abstract class AbstractSimilarity
extends java.lang.Object
implements DistanceMeasure

Abstract super class for all similarity measures. A similarity measure quantifies the distance between two instances. Low values denote more distant instances.

compare

public boolean compare(double x,
                       double y)

Description copied from interface: DistanceMeasure

Returns whether the first distance, similarity or correlation is better than the second distance, similarity or correlation. Both values should bee calculated using the same measure. For similarity measures the higher the similarity the better the measure, for distance measures it is the lower the better and for correlation measure the absolute value must be higher.

Specified by:

compare in interface DistanceMeasure

Parameters:

x - the first distance, similarity or correlation

y - the second distance, similarity or correlation

Returns:

true if the first distance is better than the second, false in other cases.
