1. abstract class Estimator[M <: Model[M]] extends PipelineStage

   :: DeveloperApi :: Abstract class for estimators that fit models to data.

2. abstract class Model[M <: Model[M]] extends Transformer

   :: DeveloperApi :: A fitted model, i.

3. class Pipeline extends Estimator[PipelineModel]

   :: Experimental :: A simple pipeline, which acts as an estimator.

4. class PipelineModel extends Model[PipelineModel] with Logging

   :: Experimental :: Represents a fitted pipeline.

5. abstract class PipelineStage extends Params with Logging

   :: DeveloperApi :: A stage in a pipeline, either an Estimator or a Transformer.

6. abstract class PredictionModel[FeaturesType, M <: PredictionModel[FeaturesType, M]] extends Model[M] with PredictorParams

   :: DeveloperApi :: Abstraction for a model for prediction tasks (regression and classification).

7. abstract class Predictor[FeaturesType, Learner <: Predictor[FeaturesType, Learner, M], M <: PredictionModel[FeaturesType, M]] extends Estimator[M] with PredictorParams

   :: DeveloperApi :: Abstraction for prediction problems (regression and classification).

8. abstract class Transformer extends PipelineStage

   :: DeveloperApi :: Abstract class for transformers that transform one dataset into another.

9. abstract class UnaryTransformer[IN, OUT, T <: UnaryTransformer[IN, OUT, T]] extends Transformer with HasInputCol with HasOutputCol with Logging

   :: DeveloperApi :: Abstract class for transformers that take one input column, apply transformation, and output the result as a new column.
