Perform Feature Engineering Using Amazon SageMaker

Imagine you are the data engineer, and you have been assigned the task of preprocessing the data and getting it ready for the machine learning engineers to create a highly predictable model. Your data contains both text and numerical data. The numerical data is of different ranges, and some text features require proper ordering. In this hands-on lab, you will learn how to encode, scale, and bin the data using scikit-learn.
