> ML Tuning Cross-Validation Improvements
> ---------------------------------------
>
> Key: SPARK-8983
> URL: https://issues.apache.org/jira/browse/SPARK-8983
> Project: Spark
> Issue Type: Umbrella
> Components: ML
> Reporter: Feynman Liang
> Priority: Major
> Labels: bulk-closed
>
> This is an umbrella for grouping together various improvements to pipelines
> tuning features, centralizing developer communication, and encouraging code
> reuse and common interfaces.
> We currently only support k-fold CV in {{CrossValidator}} while competing
> packages (e.g. [R caret|http://topepo.github.io/caret/splitting.html]) are
> much more feature rich, supporting balanced class labels, hold-out for
> time-series data, etc.
