Description

Another step in the Pipeline could be a feature transformation step, that could be after the feature creation one and before the fitting of the model. However, if we want to have an interface similar to the one of the FeatureCreation class where a list of FeatureTransformation classes are passed and applied sequentially, this requires some reasoning in order to design a good interface.
Some thoughts:

  • Some features, like PCA, require a fit step, while some other do not.
  • Features should have input columns (the ones to transform) and output columns (and drop the others). What should be the interface for this?
