## Machine Learning University: Decision Trees and Ensemble Methods Class

This repository contains __slides__, __notebooks__, and __datasets__ for the __Machine Learning University (MLU) Decision Trees and Ensemble Methods__ class. Our mission is to make Machine Learning accessible to everyone. We have courses available across many topics of machine learning and believe knowledge of ML can be a key enabler for success. This class is designed to help you get started with tree based models, learn about widely used Machine Learning techniques and apply them to real-world problems.
