Intended learning outcomes:
When successfully completing this module, the students have acquired soft skills and technical expertise, as follows: SOFT SKILLS: They

• have learned how to critically discuss and valuate a scientific paper

TECHNICAL EXPERTISE: They

• comprehend the business context of recommenders
• comprehend the different types of recommenders, their advantages and disadvantages from the business perspective and from the mining perspective and are familiar with advanced recommendation methods
• have acquired advanced insights on how to critically evaluate a recommender from the mining perspective and the business perspective
• understand why adaption is necessary in recommenders and comprehend the behaviour of temporal methods for recommenders

and have thus acquired skills they need in order to critically appreciate off-the-shelf or state-of-the-art methods and to design workflows that encompass recommender learning, tuning and evaluation

Content:
The course consists of two blocks:

• Block 1 is on Fundamentals of Recommenders and has mutiple parts: (1.1) recommender goals and workflows, (1.2) simple recommendation methods, (1.3) evaluation mechanisms, (1.4) recommender adaption on a stream
• Block 2 covers advanced topics of recommenders: students read and critically discuss papers in class
