    I'm beyond excited to finally announce my new book "Feature Engineering A-Z" 🎉

    The vision for the book is to be a comprehensive collection of feature engineering methods. Describing how they work, when and why you should and shouldn't use it. Code snippets in both R and Python!

    I have been working on this project over the last couple of years. Please read it if this interests you! Always looking for feedback!
