Towards Minimal Necessary Data: The Case for Analyzing Training Data Requirements of Recommender Algorithms

This paper states the case for the principle of minimal necessary data: If two recommender algorithms achieve the same effectiveness, the better algorithm is the one that requires less user data. Applying this principle involves carrying out training data requirements analysis, which we argue should be adopted as best practice for the...

The Potentials of Recommender Systems Challenges for Student Learning

Increasingly, educators make use of learning-by-doing approaches to teach studentsof STEM programmes the skills that they need to become successful incareers in research and development. However, we argue that the technicalchallenges addressed in these programmes are often too limited and thereforedo not support the students in gaining the more...
