新的CoFire方法通过保持初始答案的可靠性来改进视频理解模型

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-28 04:00

研究人员开发了一种名为CoFire的新型强化学习方法，以改进视频理解模型。该方法解决了“置信度侵蚀”问题，即学习过程可能降低初始答案的可靠性。CoFire确保在反思之前初始答案保持可靠，与标准的成果奖励RL相比，初始答案准确率平均提高了4.1个百分点，最终准确率提高了3.7个百分点。该方法在Video-MME、MLVU和LongVideoBench等基准数据集上达到了67.0%的平均准确率，比一个可比的7B方法高出1.7个百分点。 AI

影响增强了视频理解模型的可靠性，有望提高需要准确识别时刻的应用的性能。

先自信，后反思：用于视频理解的置信度保持反思强化学习

arXiv:2610.36467v1 Announce Type: new Abstract: Video models answer from sampled frames and may miss the decisive moment. A common remedy is to commit to an answer, re-examine the video, and confirm or revise it, a loop now mainly learned with reinforcement learning (RL). We find…
