Description copied from interface: ClusterDissimilarity

Provides the notion of distance, or dissimilarity, between two data points

Parameters:

a - the first data point

b - the second data point

Returns:

a value >= 0 that is a measure of the difference between the two points. The closer to zero, the more similar the points are.
