1.  case class FeatureRotator(baseLearner: Learner) extends Learner with Product with Serializable

   Rotate the training data before passing along to a base learner

   Rotate the training data before passing along to a base learner

   This may be useful for improving randomization in random forests, especially when using random feature selection without bagging.

7.  case class Standardizer(baseLearner: Learner) extends Learner with Product with Serializable

   Standardize the training data to zero mean and unit variance before feeding it into another learner

   Standardize the training data to zero mean and unit variance before feeding it into another learner

   This is particularly helpful for regularized methods, like ridge regression, where the relative scale of the features and labels is important.
