Feature Engineering A-Z

This repository contains the source material for the book "Feature Engineering A-Z". The rendered book can be found at https://feaz-book.com/

Installation

This book shows examples in both R and Python, with renv being used to manage R dependencies and uv being used to manage Python dependencies.

You do this by calling renv::restore() from R, and uv sync from the terminal. The latter creates a virtual environment in .venv/.

The book is rendered using Quarto. For this to work smoothly, the environment variable RETICULATE_PYTHON should point at .venv/bin/python, which is specified in .Renviron.
