Module with some basic similarities between vectors
Functions
cosine |
Computes the cosine similarity between two sparse vectors. It returns 0.0 if one of the vectors has null norm. |
jaccard |
Computes the extended Jaccard similarity between two sparse vectors. |
pearson |
Computes the Pearson correlation index between two sparse vectors. It treats the vectors as discrete uniform random variables. |
