Feature Engineering
Let's engineer some features for the Tweet ranking model.
The machine learning model is required to predict user engagement on user A’s Twitter feed. Let’s engineer features to help the model make informed predictions.
📝 The feature set shown here is the result of one brainstorm session. However, feature engineering is an iterative process. As an exercise, you are encouraged to think about more features.

- The logged-in user
- The Tweet
- Tweet’s author
- The context
