Why One-Hot Encode Data in Machine Learning?

Last Updated on June 30, 2020 Getting started in applied machine learning can be difficult, especially when working with real-world data. Often, machine learning tutorials will recommend or require that you prepare your data in specific ways before fitting a machine learning model. One good example is to use a one-hot encoding on categorical data. Why is a one-hot encoding required? Why can’t you fit a model on your data directly? In this post, you will discover the answer to […]
