[SPARK-18724][ML] Add TuningSummary for TrainValidationSplit ## What changes were proposed in this pull request? jira: https://issues.apache.org/jira/browse/SPARK-18724 Currently TrainValidationSplitModel only provides tuning metrics in the format of Array[Double], which makes it harder for tying the metrics back to the paramMap generating them and affects the usefulness for the tuning framework. Add a Tuning Summary to provide better presentation for the tuning metrics, for now the idea is to use a DataFrame listing all the params and corresponding metrics. The Tuning Summary Class can be further extended for CrossValidator. ## How was this patch tested? existing and new unit tests You can merge this pull request into a Git repository by running: $ git pull https://github.com/hhbyyh/spark tuningsummary Alternatively you can review and apply these changes as the patch at: https://github.com/apache/spark/pull/16158.patch To close this pull request, make a commit to your master/trunk branch with (at least) the following in the commit message: This closes #16158 ---- commit d1e22d58f5ecb5972f2ea528dc18d1230d678424 Author: Yuhao <yuhao.y...@intel.com> Date: 2016-12-03T00:49:29Z tuning summary commit a7cfa63c755c5760af1bd706f71a930d742a21ad Author: Yuhao <yuhao.y...@intel.com> Date: 2016-12-05T18:50:41Z Merge remote-tracking branch 'upstream/master' into tuningsummary commit ad73c12fedbfd0b2348515c6b96766b5fa55c52a Author: Yuhao <yuhao.y...@intel.com> Date: 2016-12-05T22:06:32Z add ut commit 425a41990b813dd68479c73249ebb7790e6f331e Author: Yuhao <yuhao.y...@intel.com> Date: 2016-12-05T22:19:55Z add comments ---- --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well.
