Subject [jira] [Created] (IGNITE-13386) [ML] Add more distances between two Vectors (Part 2)
Date Wed, 26 Aug 2020 13:08:00 GMT
Alexey Zinoviev created IGNITE-13386:
----------------------------------------

             Summary: [ML] Add more distances between two Vectors (Part 2)
                 Key: IGNITE-13386
                 URL: https://issues.apache.org/jira/browse/IGNITE-13386
             Project: Ignite
          Issue Type: Sub-task
          Components: ml
            Reporter: Alexey Zinoviev
            Assignee: Mark Andreev


Mark suggested to add more distances, below his letter about topic

[http://apache-ignite-developers.2346864.n4.nabble.com/First-contribute-to-Ignite-ML-td48950.html]

"Currently, Ignite supports only these distances
(org.apache.ignite.ml.math.distances) :
- ChebyshevDistance
- CosineSimilarity
- EuclideanDistance
- HammingDistance
- JaccardIndex
- ManhattanDistance
- MinkowskiDistance

But in scipy (
[https://docs.scipy.org/doc/scipy/reference/spatial.distance.html]) we can
find at least:
- BrayCurtis
- Canberra
- Jensen-Shannon
- Seuclidean
- Weighted Minkowski

I can implement those and coverage with unit tests."
