新基准揭示视频模型遗忘长期上下文

研究人员推出SceneBench,一个旨在评估视频理解模型在长视频中(尤其是在不同场景之间)保持上下文能力的新基准。他们的发现表明,当前的视觉语言模型(VLMs)在被问及需要对扩展时间信息进行推理的问题时,会表现出显著的遗忘。为了解决这个问题,他们提出了Scene-RAG,一种检索增强生成方法,通过动态整合跨场景的相关上下文,将VLM性能提高了2.50%,凸显了在为VLM开发稳健的长上下文保留能力方面持续存在的挑战。 AI

影响 强调了当前VLMs在长上下文视频理解方面的局限性,可能指导未来研究朝着更稳健的时间推理能力发展。

    场景感知很重要:利用场景感知长视频基准揭示视频理解模型的遗忘现象

    arXiv:2603.27259v2 Announce Type: replace Abstract: Long video understanding (LVU) remains a core challenge in multimodal learning. Although recent vision-language models (VLMs) have made notable progress, existing benchmarks mainly focus on either fine-grained perception or coar…
