Greedy linear models without exploration consistently achieve top-tier performance in over 90% of offline dataset evaluations for linear bandit recommenders, with hyperparameter tuning favoring minimal exploration and exposing biases in these protocols.
Data portability scenarios in algorithmic pluralism produce varying effects on user utility across different recommendation algorithms.
