Let’s Do: Feature Engineering

A brief exhibition of the power of simple feature engineering using house sale price data and a LightGBM model.

A brief background

Feature engineering can mean different things to different people, but the term largely covers the process of identifying, manipulating, and transforming information in order to improve the predictive power of a model.

The process can be broken down into more specific stages (neither exhaustive nor sequential):
