---------------------------------------------------------------
Some notes:
In PR #6322:
1. Estimator/Transformer/ doesn’t need to extend Params since PipelineStage
already does.
1. Move Evaluator to ml.evaluation.
1. Mention larger metrics are better.
1. PipelineModel doc. “compiled” -> “fitted”
1. Hide PolynomialExpansion.expand
1. Hide VectorAssembler.
1. Word2Vec.minCount -> @param
1. ParamValidators -> DeveloperApi
1. Hide MetadataUtils/SchemaUtils.
Others:
1. @varargs to setDefault (SPARK-7498)
1. Update RegexTokenizer default setting. (SPARK-7794)
1. Mention `RegexTokenizer` in `Tokenizer`. (SPARK-7794)
1. Remove Params.validateParams(paramMap)?
1. param and getParam should be final (SPARK-7816)
1. UnresolvedAttribute (Java compatibility?)
1. Missing RegressionEvaluator (SPARK-7404)
1. ml.feature missing package doc (SPARK-7808)
1. ALS -> use dataframes to store user/item factors? Then we can hide ALS.Rating
1. ALSModel -> remove training parameters?

> Audit Pipeline APIs for 1.4
> ---------------------------
>
> Key: SPARK-7535
> URL: https://issues.apache.org/jira/browse/SPARK-7535
> Project: Spark
> Issue Type: Sub-task
> Components: ML, PySpark
> Reporter: Joseph K. Bradley
> Assignee: Xiangrui Meng
>
> This is an umbrella for auditing the Pipeline (spark.ml) APIs. Items to
> check:
> * Public/protected/private access
> * Consistency across spark.ml
> * Classes, methods, and parameters in spark.mllib but missing in spark.ml
> ** We should create JIRAs for each of these (under an umbrella) as to-do
> items for future releases.
> For each algorithm or API component, create a subtask under this umbrella.
> Some major new items:
> * new feature transformers
> * tree models
> * elastic-net
> * ML attributes
> * developer APIs (Predictor, Classifier, Regressor)
