From AutoRecSys to AutoRecLab: A Call to Build, Evaluate, and Govern Autonomous Recommender-Systems Research Labs

Joeran Beel, Bela Gipp, Tobias Vente +2

Recommender-systems research has accelerated model and evaluation advances, yet largely neglects automating the research process itself. We argue for a shift from narrow AutoRecSys…

Green Recommender Systems: Understanding and Minimizing the Carbon Footprint of AI-Powered Personalization

Lukas Wegmeth, Tobias Vente, Alan Said +1

As global warming soars, the need to assess and reduce the environmental impact of recommender systems is becoming increasingly urgent. Despite this, the recommender systems commun…

APS Explorer: Navigating Algorithm Performance Spaces for Informed Dataset Selection

Tobias Vente, Michael Heep, Abdullah Abbas +3

Dataset selection is crucial for offline recommender system experiments, as mismatched data (e.g., sparse interaction scenarios require datasets with low user-item density) can lea…

e-Fold Cross-Validation for Recommender-System Evaluation

Moritz Baumgart, Lukas Wegmeth, Tobias Vente +1

To combat the rising energy consumption of recommender systems we implement a novel alternative for k-fold cross validation. This alternative, named e-fold cross validation, aims t…

From Theory to Practice: Implementing and Evaluating e-Fold Cross-Validation

Christopher Mahlich, Tobias Vente, Joeran Beel

This paper introduces e-fold cross-validation, an energy-efficient alternative to k-fold cross-validation. It dynamically adjusts the number of folds based on a stopping criterion.…
