The Netflix Challenge and what it has to do with math!

Netflix, Amazon, Zalando and others are focusing on one thing in particular when it comes to customer loyalty: good recommendations for new products, movies, clothing, etc. that are customized to the user. To this end, these companies develop recommendation systems that can predict as well as possible what the respective user might like.

To further improve its own recommendation system, Netflix set up a challenge in 2006: The team that could predict at least 10% more accurately which movies a user would like had a chance to win the grand prize of $1 million!

In the workshop you will work with the original data from the Netflix Challenge and develop your own recommendation system. You will apply common strategies from the field of machine learning.
