turicreate.toolkits.distances. jaccard(x, y)¶

Compute the Jaccard distance between between two dictionaries. Suppose \(K_x\) and \(K_y\) are the sets of keys from the two input dictionaries.

\[D(x, y) = 1 - \frac{|K_x \cap K_y|}{|K_x \cup K_y|}\]

Notes

• Jaccard distance treats the keys in the input dictionaries as sets, and ignores the values in the input dictionaries.
