Due to the extreme information overload on the web, we need models that can process information in a personalized way. One class of such models are Recommender Systems (RS). The core of RS are machine learning algorithms focusing on user feedback. RS aim to predict users’ future preferences and provide them with surprising, yet relevant objects. This course covers common working principles of recommender systems, its learning methods, data types, requirements and evaluation as well as some aspects of the practical deployment.
