yuhao yang commented on SPARK-7128:
-----------------------------------
I would vote for adding this now.
This is quite helpful in practical applications like fraud detection, and
feynmanliang has started with a solid prototype. I can help finish it if this
is on the roadmap.
> Add generic bagging algorithm to spark.ml
> -----------------------------------------
>
> Key: SPARK-7128
> URL: https://issues.apache.org/jira/browse/SPARK-7128
> Project: Spark
> Issue Type: New Feature
> Components: ML
> Reporter: Joseph K. Bradley
>
> The Pipelines API will make it easier to create a generic Bagging algorithm
> which can work with any Classifier or Regressor. Creating this feature will
> require researching the possible variants and extensions of bagging which we
> may want to support now and/or in the future, and planning an API which will
> be properly extensible.
> Note: This may interact some with the existing tree ensemble methods, but it
> should be largely separate since the tree ensemble APIs and implementations
> are specialized for trees.
