Building Decision Trees by Hand without Code

 Cool little piece that is instructional and even inspirational.   Math and process seen together to produce real value.

Random Forest and Decision Trees by hand — no coding

By Thomas Le Menestrel,      Computational Engineering student at Stanford | Passionate about Machine Learning and Data Science  in TowardsDataScience 

Introduction

In this article, we will discuss Decision Trees and Random Forest, two algorithms used in Machine Learning for classification and regression tasks.

I will show how to build a Decision Tree from scratch using a pen and paper and how to generalise this and build a Random Forest model.

Dataset

Let’s see how this work in practice with a simple dataset. .... ( much more )
