skill PathFeature Engineering

The key to building high-quality, reliable machine learning models is feeding that model high-quality data. Feature Engineering is an essential–though sometimes overlooked–step in ensuring the quality of your data. Feature Engineering is the process of taking raw data, scaling it, normalizing it, and transforming it so it can be used by your machine learning model. It’s the process of turning your attributes into features, and ensuring that the data you are using meets the assumption of the model you are training.
