English(EN) TimeThink: Reasoning with Time for Video LLMs

TimeThink框架增强视频大语言模型的时间推理能力 · arXiv论文

研究人员推出TimeThink,一个新颖的强化学习框架,旨在增强视频大语言模型(Video-LLMs)的时间推理能力。该方法通过将时间线索步骤视为核心优化原语,专注于优化长视频序列中相关时间证据的发现。TimeThink利用分步时间过程奖励进行局部信用分配,并结合过程-结果优化目标来提高推理准确性和任务正确性。该框架得到了TimeThink-RFT-20K数据集的支持,该数据集包含自动提取的时间证据片段,并在各种视频理解基准测试中展示了开源视频强化学习模型中的最先进性能。 AI

影响 该框架通过改进视频模型处理时间信息的方式,有望带来更准确、更高效的视频理解模型。
