WebFeature engineering is the process of transforming raw data into features that better represent the underlying problem to the predictive models, resulting in improved model accuracy on unseen data. I believe many would say that feature engineering is a part of data cleansing. Most don’t call it data preprocessing. WebJul 14, 2024 · Feature engineering is about creating new input features from your existing ones. In general, you can think of data cleaning as a process of subtraction and feature engineering as a process of addition. All data scientists should master the process of engineering new features, for three big reasons:
