Answer
- A Selecting features based on their contribution to model performance
- E Extracting a subset of informative, non-redundant features from existing ones
Explanation
Feature engineering includes selecting relevant features based on their contribution to model performance and extracting informative, non-redundant features to reduce training times and computational costs. Anonymizing and imputing belong to preprocessing, and gathering from sensors to data acquisition.
