Machine Learning Exercises

This repository contains the Python exercises accompanying the theory from my machine learning book.

Also have a look at the cheat sheet, which includes a summary of the most important steps when developing a machine learning solution, incl. code snippets.

If you're unfamiliar with Python, please have a look at this tutorial first, which also includes some notes on how to install Python and Jupyter Notebook on your own computer (please make sure you're using Python 3 and all libraries listed in the requirements.txt file are installed and up to date (you can also verify this with the test_installation.ipynb notebook). If you have a Google account, you can also run the code in the cloud using Google Colab:

If you have any questions, please drop me a line at hey[at]franziskahorn.de.

Have fun!
