Rethinking RL Evaluation: Can Benchmarks Truly Reveal Failures of RL Methods? (2026.findings-acl)
Copied to clipboard
| Challenge: | Existing benchmarks for reinforcement learning for large language models do not accurately assess generalization. |
| Approach: | They propose three core principles for designing more faithful benchmarks: sufficient difficulty, balanced evaluation, and distributional robustness. |
| Outcome: | The proposed benchmarks do not accurately assess generalization across distribution shifts, difficulty levels, and counterfactual scenarios. |
