Method Detail

similarity

double similarity(SparseVector first,
                  SparseVector second)

Calculates the similarity between two SparseVectors.

Parameters:

first - The first SparseVector.

second - The second SparseVector.

Returns:

A value between 0 and 1, where 1 is most similar and 0 is least similar.
