About this skill path

A machine learning model is only as good as the data it learns from. Feature Engineering helps ensure data quality by scaling, normalizing, and transforming raw data before using it in a machine learning model. In this Skill Path, you will learn to safeguard data quality, turn attributes into features, and verify that your data meets the assumptions of the model you want to train.

Skills you'll gain

  • Turn raw data into features
  • Select the right features for a model
  • Implement principal component analysis
