Joseph K. Bradley updated SPARK-18334:
--------------------------------------
Summary: What hashDistance should MinHash use? (was: MinHash should use
binary hash distance)
> What hashDistance should MinHash use?
> -------------------------------------
>
> Key: SPARK-18334
> URL: https://issues.apache.org/jira/browse/SPARK-18334
> Project: Spark
> Issue Type: Bug
> Reporter: Yun Ni
> Priority: Trivial
>
> MinHash currently is using the same `hashDistance` function as
> RandomProjection. This does not make sense for MinHash because the Jaccard
> distance of two sets is not relevant to the absolute distance of their hash
> buckets indices.
> This bug could affect accuracy of multi probing NN search for MinHash.
