Method Detail

getDistance

public float getDistance(double[] object1,
                         double[] object2)
                  throws Exception

Description copied from interface: IDistanceFunction

Distance should be large if objects are "far away" from each other, i.e. dissimilar.

Specified by:

getDistance in interface IDistanceFunction<double[]>

Returns:

the distance

Throws:

Exception

getNativeComparison

public float getNativeComparison(double[] o1,
                                 double[] o2)
                          throws Exception

Description copied from interface: IDistanceFunction

Calculates native comparison index between two objects (distance or similarity). Similarity is large if objects are similar to each other, in contrast with IDistanceFunction.getDistance(Object, Object).

Specified by:

getNativeComparison in interface IDistanceFunction<double[]>

Returns:

the distance

Throws:

Exception

toString

public String toString()

Overrides:

toString in class Object
