distance

public double distance(Value f,
                       Value s)

Implements distance of interface DistanceMetric distance(v1,v2) = lambda * distance(v1.aset,v2.aset) + (1-lambda)*distance(v1.bset,v2.bset) User can set the lambda value but it should be in [0,1] using Dice coefficient on two given sets

Specified by:

distance in interface DistanceMetric

Parameters:

f - and s must be StringTwoSetValues

Returns:

distance(f,s) as defined above
