# Is there a difference between Vectorization and Featurization?

I have come across articles that mention Featurization and Vectorization interchangeably. Is there a minute difference between each other or are they exactly referring to the same thing?

Outside of a given article, I would not want to use them interchangeably. Usually "vectorization" refers to modifying an operation so that it works with vectors rather than scalars. (this is what numpy.ndarray is all about).
