> Optimizations for ML Pipeline Tuning
> ------------------------------------
>
> Key: SPARK-19071
> URL: https://issues.apache.org/jira/browse/SPARK-19071
> Project: Spark
> Issue Type: Improvement
> Components: ML
> Reporter: Bryan Cutler
> Priority: Major
> Labels: bulk-closed
>
> This is a parent task to plan the addition of optimizations in ML tuning for
> parallel model evaluation and more efficiency with pipelines. They will
> benefit Crossvalidator and TrainValidationSplit when performing a parameter
> grid search. The proposal can be broken into 3 steps in order of simplicity:
> 1. Add ability to evaluate models in parallel.
> 2. Optimize param grid for pipelines, as described in SPARK-5844
> 3. Add parallel model evaluation to the optimized pipelines from step 2
> See the linked design document for details on the proposed implementation.
