**What it does**

This tool provides several transformer classes to change raw feature vectors into a representation that is more suitable for the downstream estimators. The library is provided by sklearn.preprocessing package.

For information about preprocessing classes and parameter settings please refer to `Scikit-learn preprocessing`_.
