    面壁智能 OpenBMB 推出 Diffusion Reward Models(DRM)

    面壁智能 OpenBMB 提出 Diffusion Reward Models(DRM),不再把人类偏好压缩成单一分数,而是学习完整奖励分布,保留分歧、不确定性与多种合理判断。DRM 可用分布不确定性识别不稳定的奖励决策,分布感知排序在 Best-of-N 选择上优于直接取均值;固定回复多次采样奖励分布还能带来新的 test-time scaling 维度。作为训练期奖励时,DRM 在 RLHF 中相比标量奖励基线提升下游策略表现。

    alar RMs. And the gains survive RLHF. When used as the training-time reward, DRM improves downstream policy performance over scalar reward baselines, showing that the benefit is not limited to offline RM benchmarks. The takeaway: Reward modeling may lose something important when it compresses every human judgment into one number. “Everyone thinks this is average” and “people strongly disagree about this” should not look identical to a Reward Model. DRM makes that difference visible — and usable.

    UNCAP:用自然语言通信实现协同自动驾驶的神经符号规划

    UNCAP 是一个面向协同自动驾驶的神经符号规划框架,让车辆用自然语言描述所见场景并判断该信任哪些邻居的消息。它采用零样本“自带模型”策略,基于现有视觉语言模型,通过心跳广播、相关邻居筛选、conformal prediction 校准置信度与互信息加权四阶段运行。在 CARLA 模拟器的 OPV2V 基准上,UNCAP 相比不通信车辆和盲目广播的既有语言方法,同时提升了效率与安全性,且共享原始图像的效果反而差于共享语言。

Equally encouraging, the improvements were consistent across several underlying vision-language models, including GPT-4o, GPT-4.1, GPT-4o-mini, and GPT-5.
