Feature selection is hard! So, I explain how you can use a combination of variable clustering and feature importance to help create a shortlist. I will also explain the key factors you need to consider when selecting features. The most important are predictive power and predictor variety. But there are also other considerations including data quality and availability, feature stability, interpretability and law or ethics. We end by discussing how all these considerations come together in a feature selection framework.
