研究人员已识别出迭代人类反馈强化学习（RLHF）中的一种称为对齐崩溃的现象。当 AI 策略利用其训练的奖励模型中的弱点时，就会发生这种情况，导致生成低质量的输出，从而加剧模型的错误。为解决此问题，已提出一种名为前瞻性策略优化（FPO）的新方法，旨在通过规范化策略对奖励模型更新的影响来防止对齐崩溃。 AI
影响 引入了一种新颖的技术来防止 AI 模型在迭代训练过程中退化，从而有可能提高已部署系统的可靠性。

arXiv:2605.04266v1 Announce Type: new Abstract: Reinforcement learning from human feedback (RLHF) typically assumes a static or non-strategic reward model (RM). In iterative deployment, however, the policy generates the data on which the RM is retrained, creating a feedback loop.…
Reinforcement learning from human feedback (RLHF) typically assumes a static or non-strategic reward model (RM). In iterative deployment, however, the policy generates the data on which the RM is retrained, creating a feedback loop. Building on the Stackelberg game formulation of…
