Joseph K. Bradley commented on SPARK-5992:
------------------------------------------
I'm just noting here that [~yuu.ishik...@gmail.com] and I discussed the design
doc. The current plan is to have these implemented under ml.feature, with 2
types of UnaryTransformers:
* Vector -> T: hash feature vector to some other type (Vector, Int, etc.)
* Vector -> Double: compare feature vector with a fixed base Vector, and return
similarity
> Locality Sensitive Hashing (LSH) for MLlib
> ------------------------------------------
>
> Key: SPARK-5992
> URL: https://issues.apache.org/jira/browse/SPARK-5992
> Project: Spark
> Issue Type: New Feature
> Components: MLlib
> Affects Versions: 1.4.0
> Reporter: Joseph K. Bradley
>
> Locality Sensitive Hashing (LSH) would be very useful for ML. It would be
> great to discuss some possible algorithms here, choose an API, and make a PR
> for an initial algorithm.
