Computes the estimated Jaccard similarity of two objects that have MinHash signatures.
Another signature to similarity against.
Returns the estimated Jaccard similarity of two signatures, which is defined as the number of elements in the signature that agree over the total length of the signature.
This signature must be the same length as the signature we are comparing to. We do not perform this check; we delegate this check to the function caller.
Goes from hash array to an MLLib vector.
A dense vector that can be used in MLLib.
