摘要
一种名为S2T-RLHF的新框架被引入，以提高来自人类反馈的强化学习（RLHF）的稳定性。这种创新方法将重点从令牌级奖励转移到句子级奖励，从而帮助减轻通常由噪声偏好信号引起的不稳定性。通过实施层次信用分配，S2T-RLHF增强了训练过程的鲁棒性，并确保与人类偏好的更好对齐，可能导致更可靠的AI系统。
A new framework called S2T-RLHF has been introduced to improve the stability of reinforcement learning from human feedback (RLHF). This innovative approach shifts the focus from token-level rewards to sentence-level rewards, which helps mitigate the instability often caused by noisy preference signals. By implementing hierarchical credit assignment, S2T-RLHF enhances the robustness of the training process and ensures better alignment with human preferences, potentially leading to more reliable AI systems.
