In the machine learning context, feature engineering is the process of extracting attributes and variables from raw data to make it suitable for training an AI model. This step is crucial as it transforms raw data into meaningful features that can improve the model's accuracy and performance. Feature engineering involves selecting, modifying, and creating new features that help the model learn more effectively.

I'm a little confused by the wording of the options. Converting raw data to clean data, creating a learning schema, and developing guidelines all sound like they could be part of feature engineering. I'll have to re-read the question a few times to make sure I understand it.
