  • TLDR:PLC-DPO is proposed to robustly optimize preferences by routing each pair's training signal as a clean, flip, or tie case, which reframes noisy preference learning as actively correcting supervision direction and strength rather than merely filtering suspicious examples.

  • TLDR中文:PLC-DPO 将每个偏好对的训练信号路由为 clean、flip 或 tie 三类,将噪声偏好学习从单纯过滤可疑样本重构为主动修正监督方向与强度。
