Xusen Yin updated SPARK-14299:
------------------------------
Description:
Duplicated code that I found in scala/examples/ml:
* scala/ml
** CrossValidatorExample.scala --> ModelSelectionViaCrossValidationExample
** DecisionTreeExample.scala --> DecisionTreeRegressionExample,
DecisionTreeClassificationExample
** GBTExample.scala --> GradientBoostedTreeClassifierExample,
GradientBoostedTreeRegressorExample
** LinearRegressionExample.scala --> LinearRegressionWithElasticNetExample
** LogisticRegressionExample.scala --> LogisticRegressionWithElasticNetExample,
LogisticRegressionSummaryExample
** RandomForestExample.scala --> RandomForestRegressorExample,
RandomForestClassifierExample
** TrainValidationSplitExample.scala -->
ModelSelectionViaTrainValidationSplitExample
** DeveloperApiExample.scala --> I delete it for now because it's only about
how to create your own classifieri, etc, which can be learned easily from other
examples and ml codes.
** SimpleParamsExample.scala --> merge with
LogisticRegressionSummaryExample.scala
** SimpleTextClassificationPipeline.scala -->
ModelSelectionViaCrossValidationExample
** DataFrameExample.scala --> merge with LogisticRegressionSummaryExample.scala
When merging and cleaning those code, be sure not disturb the previous example
on and off blocks.
I'll take this one as an example.
