Reliability and Learnability of Human Bandit Feedback for Sequence-to-Sequence Reinforcement Learning (P18-1)
Copied to clipboard
| Challenge: | Recent work has shown that reinforcement learning (RL) can be scaled to games with large state-action spaces, achieving human-level performance or even superhuman performance. |
| Approach: | They propose to use bandit feedback to improve sequence-to-sequence learning by simulating reward signals by evaluation metrics such as BLEU, F1-score, or ROUGE. |
| Outcome: | The proposed methods improve performance even from small amounts of human feedback, pointing to a great potential for applications at larger scale. |
