Course Overview

Decision trees and random forests are tools that every data scientist or machine learning practitioner should be familiar with. Famous for producing good predictors, these methods are also indispensable when it comes to understanding the problem at hand, as well as visualizing and communicating your results. That’s why we have prepared this course for you. The first part features a thorough explanation of the workings of decision trees, how to code and visualize them with sklearn, and the pros and cons you should consider. Then we will build on the concept of a single decision tree to produce the random forest algorithm. Finally, we will cap it all off with a practical example implementing both decision trees and random forests in Python to predict a person’s income based on census data.

Excellent. we need more courses like this. and we would want courses to help us know which ML algorithms would be best suited for a particular problem

Not mathematically sound. Should have also included feature importance obtained from random forest

“The ability to interpret a model’s results is indispensable in Machine Learning. That’s where decision trees come into play. The decision tree model is relatively simple and easy to understand – both characteristics that make it a great foundation for ML enthusiasts to grasp and visualize basic concepts.”
