Joseph K. Bradley commented on SPARK-7000:
------------------------------------------
Decision after conferring with [~mengxr]: The structure will be:
* ml.Predictor (Predictor will be made public and moved to the ml package in
[SPARK-5995])
* ml.trees.* (Tree abstractions shared by ml.classification and ml.regression)
* ml.ensembles.* (Generic ensemble abstractions shared by ml.classification and
ml.regression)
Since we can't think of more shared abstractions currently, we'll aim for a
flatter directory structure. Closing this JIRA
> spark.ml Prediction abstractions should reside in ml.prediction subpackage

> Key: SPARK-7000
> URL: https://issues.apache.org/jira/browse/SPARK-7000
> Project: Spark
> Issue Type: Improvement
> Components: ML
> Affects Versions: 1.3.1
> Reporter: Joseph K. Bradley
> Assignee: Joseph K. Bradley
> Priority: Minor
>
> spark.ml prediction abstractions are currently not gathered; they are in both
> ml.impl and ml.tree. Instead, they should be gathered into ml.prediction.
> This will become more important as more abstractions, such as ensembles, are
> added.
