腾讯犀牛鸟精英人才计划发布三篇ICML 2026入选论文：高效蒸馏、长上下文推理与稀疏视角视频生成
英文摘要
The Tencent Rhino Bird Elite Talent Program released three papers accepted at ICML 2026. The first, Hybrid Policy Distillation (HPD), unifies forward and reverse KL divergence and on/off-policy data to improve LLM distillation stability, efficiency, and performance across math reasoning, dialogue, and code generation. The second, Many-Shot CoT-ICL, studies in-context learning with many chain-of-thought examples for reasoning tasks, finding that similarity-based retrieval fails and proposing CDS, a method that orders examples by conceptual progression to boost reasoning accuracy by 3.81% on average. The third, CamGeo, distills 3D geometry priors from a video-to-3D model into a diffusion backbone via trajectory and cross-frame consistency distillation and a coarse-to-fine curriculum, achieving stable performance gains in sparse camera-conditioned image-to-video generation.
中文摘要
腾讯犀牛鸟精英人才计划发布了三篇被ICML 2026录用的论文。第一篇《Hybrid Policy Distillation for LLMs》提出融合正向与反向KL散度及在/离策略数据的混合策略蒸馏（HPD），在数学推理、对话和代码生成等任务上一致提升了LLM蒸馏的优化稳定性、计算效率与最终性能。第二篇《Many-Shot CoT-ICL》研究推理任务中大量思维链示例的上下文学习，发现基于相似度的检索失效，并提出按概念递进排序示例的CDS方法，使数学和叙事推理平均提升3.81%。第三篇《CamGeo》通过关键帧轨迹蒸馏和跨帧一致性蒸馏将3D几何先验注入扩散主干，并采用三阶段课程学习，在稀疏相机约束的图像到视频生成中取得了稳定的性能提升。
关键要点
Hybrid Policy Distillation (HPD) combines forward and reverse KL with on/off-policy data to unify existing LLM knowledge distillation methods, improving stability and final performance on math reasoning, dialogue, and code.
