Date Thu, 10 Nov 2016 22:57:58 GMT
Yun Ni created SPARK-18408:
------------------------------

             Summary: API Improvements for LSH
                 Key: SPARK-18408
                 URL: https://issues.apache.org/jira/browse/SPARK-18408
             Project: Spark
          Issue Type: Improvement
            Reporter: Yun Ni


As the first improvements to current LSH Implementations, we are planning to do the followings:
 - Change output schema to `Array of Vector` instead of `Vectors`
 - Use `numHashTables` as the dimension of `Array` and `numHashFunctions` as the dimension
of `Vector`
 - Rename `RandomProjection` to `BucketedRandomProjectionLSH`, `MinHash` to `MinHashLSH`
 - Make randUnitVectors/randCoefficients private
