class RandomProjectionsHasher extends Transformer with HasInputCol with HasOutputCol with HasSeed

Created by eugeny.malyutin on 05.05.16.

Implementation of Locality-sensitive hashing(similar vectors - similar hashes) via Random Binary Projection as ml.Transformer requires DataFrame with inputCol as linalg.Vector as data representation and output's Long column with HashValue

If dimensions is not set - will search AttributeGroup in metadata
