English(EN) VideoTIR: Accurate Understanding for Long Videos with Efficient Tool-Integrated Reasoning

VideoTIR 方法使用 RL 改进 LLM 的长视频理解能力

研究人员开发了 VideoTIR,一种用于改进多模态大语言模型 (MLLM) 对长视频理解能力的新颖方法。VideoTIR 利用强化学习指导 MLLM 有效地使用工具包来解析和聚焦长视频内容中有意义的片段,从而减少幻觉并提高准确性。该系统集成了工具动作分组策略优化 (TAGPO),通过分步奖励和重复利用失败尝试来提高效率,并结合了沙盒框架来生成高质量的训练数据。在三个长视频问答基准上的实验证明了 VideoTIR 的有效性和效率。 AI

影响 增强了 LLM 分析长视频内容的能力,可能改进视频搜索、摘要和内容审核等应用。

    VideoTIR:通过高效的工具集成推理实现长视频的准确理解

    arXiv:2603.25021v3 Announce Type: replace Abstract: Existing Multimodal Large Language Models (MLLMs) often suffer from hallucinations in long video understanding (LVU), primarily due to the imbalance between textual and visual tokens. Observing that MLLMs handle short visual inp…
