Jupyter Notebooks for "Ensemble Methods for Machine Learning"

This repository contains companion material: data, Python code and Jupyter notebooks for Ensemble Methods for Machine Learning (Manning Publications). The code and notebooks are released under the MIT license.

These notebooks primarily use Python 3.7, scikit-learn 0.22 and matplotlib 3.2.1, though other packages such as pandas, seaborn and Keras make guest appearances as well.

This book is a work in progress and expected to be released some time in Fall 2022.
