Beyond accuracy: evaluating recommender systems by coverage and serendipity
TL;DR: It is argued that the new ways of measuring coverage and serendipity reflect the quality impression perceived by the user in a better way than previous metrics thus leading to enhanced user satisfaction.
Proceedings ArticleDOI
Are we really making much progress? A worrying analysis of recent neural recommendation approaches
TL;DR: A systematic analysis of algorithmic proposals for top-n recommendation tasks that were presented at top-level research conferences in the last years sheds light on a number of potential problems in today's machine learning scholarship and calls for improved scientific practices in this area.

When Recurrent Neural Networks meet the Neighborhood for Session-Based Recommendation
Dietmar Jannach,Malte Ludewig +1 more
TL;DR: This work shows based on a comprehensive empirical evaluation that a heuristics-based nearest neighbor (kNN) scheme for sessions outperforms GRU4REC in the large majority of the tested configurations and datasets and ensures the scalability of the kNN method.
