Briefings

A large-scale empirical study analyzed 160,000 policies across 114 datasets to investigate how reporting choices, hyperparameter tuning, and dataset properties affect offline reinforcement learning outcomes. The study found that algorithm rankings are highly sensitive to these factors, with no single method dominating and strong methods differing substantially across environments. The research concludes that proper hyperparameter tuning frequently reshuffles perceived rankings and that benchmark composition can produce conflicting conclusions, necessitating a new dataset-conditioned recommender for practitioners.

Key points

• The study analyzed 160,000 policies across 114 datasets to investigate how reporting choices and hyperparameter tuning affect offline reinforcement learning outcomes.
• No single algorithm dominated the study, with strong methods showing substantial performance differences across environments.

Context

This research addresses a gap in systematically investigating how reporting choices, hyperparameter tuning, and dataset properties shape conclusions in offline reinforcement learning, aiming to improve research reliability.

Limitations

The evidence is limited to a single study with no additional background or context provided. Results are subject to uncertainty regarding the scale of variability and the generalizability of findings beyond the specific environments tested.
