声明

由于 TWW 团队从 2026 年 3 月公布论文至今,仍未上传训练代码和模型 checkpoints,我无法一比一复现他们的结果。

他们的 GitHub 仓库 ↗ 上只有推理代码,并且对于请求训练代码和模型权重的 issues 没有明确回应。

因此,以下的复现全部基于未经过微调的 Qwen3-VL-4B-Instruct,使用 prompt 在推理时指示模型输出 Memory Notes。

上一轮 先用 Qwen3-VL-4B-Instruct 跑通了视频问答。这一轮准备加入 TWW-like 的分段记忆:模型每看完一段视频,就写下带时间戳的 Memory Note,问题到达时再把这些记忆与近期画面一起交给模型。

结果表明加入 Memory Notes 后模型性能反而下降:在 398 个测试视频、1995 道题上,仅依靠近期画面的准确率为 72.53%,额外加入 Notes 后为 70.28%,下降 2.26 个百分点。

动机#

流式视频问答长久以来的痛点是,视频帧冗余多,但又占用大量注意力,稀释模型对较早时刻事件的关注。TWW、StreamChat 等等工作给出的解决方案就是加入 Memory 设计。

TWW 的 Memory 是从分段视频帧总结出的文本。为了教会模型输出和使用 Memory Note,团队引入了三阶段微调训练:① 有监督地学习记忆写入,并做单轮问答;② 学习多轮问答;③ 通过加入长程问题并对输入进行不确定性处理,提高模型对早期记忆的利用能力,并增强其抗干扰力。

但是,克隆仓库后我才发现,完全复现 TWW 的 pipeline 是不可行的,因为复现材料严重缺失:

  • 论文于 2026 年 3 月 12 日公开在 arXiv ↗ 上。
  • 官方仓库的首个代码提交 ↗ 为 2026 年 3 月 18 日。
  • 作者于 3 月 23 日回复权重询问 ↗,表示正在整理训练代码,checkpoint 信息之后会更新到仓库。
  • 截至 2026 年 10 月 27 日核查,仍未找到团队公开发布的训练权重 checkpoints 和训练代码。官方仓库 ↗ 仍说明目前只提供推理代码,训练代码与相关脚本待后续发布;Hugging Face 论文页 ↗ 也没有关联的模型。

这使得原版训练结果的复现和独立核验都变得困难。因此我沿用了上一次的 Qwen3-VL-4B-Instruct,没有做任何训练,仅在推理时用 prompt 提示它生成 Memory Note,并使用论文中指定的方法将 Memory Note 提供给模型进行问答。

这个实验的核心目的仅仅是测试额外的文本记忆能否提升模型回答的准确率,并没有采用 TWW 并行输入输出机制。

实验设置#

数据#

使用 StreamingBench 的 Real-Time Visual Understanding 部分(第 1~331 与 333~499 个视频,第 332 个视频解码错误)。

划分视频数题数
开发集100499
测试集3981995

两组对照#

组别回答时提供什么
近期画面(recent)问题到达前最近 30 秒的画面
近期画面 + Notes(notes)相同的近期画面,以及此前已经写入并保留的 Notes

两组使用同一个模型、相同问题、相同近期画面、相同回答提示词与解码设置。recent 的历史文本为 (none),notes 则填入已有记忆;两组均不继承先前问答内容。

记忆的构建和调用过程如下:

  1. 每看完 30 秒视频
    • 最近 30 秒画面 + 要求总结的 prompt
    • 要求 Qwen3-VL-4B-Instruct 产生一条至多 128 token 的 note
    • 附上片段时间戳,加入记忆库
  2. 问题到达
    • 最近 30 秒画面 + 已有 Notes + 问题和选项
    • 要求 Qwen3-VL-4B-Instruct 对问题输出 ABCD 回答

总结 prompt 要求模型最多写三条简短观察,关注有辨识度的实体、动作、状态、空间关系或变化;明确要求不可猜测未见事件,不应该推断意图,也不自行编造时间戳。完整提示词(下载)。

记忆库总预算为 1024 token,超出后按时间顺序移除最旧的 note。

配置#

  • Qwen3-VL-4B-Instruct,BF16,贪心解码。
  • 1 fps;每 30 秒写入记忆;近期窗口 30 秒。
  • 历史预算 1024 token;单次 Notes 最多 128 token;回答最多 32 token(仅选项)。
  • 同一批帧缓存,保持宽高比,单帧最多 131072 像素,JPEG quality=80。
  • 跨视频 batch ≤ 8;每个视频按自己的时间顺序推进。
  • GPU:NVIDIA GeForce RTX 4090。
  • PyTorch 2.13.0+cu132,Transformers 5.19.0。

结果#

方法正确 / 题数准确率
recent1447 / 199572.53%
notes1402 / 199570.28%

加入 Notes 后,准确率下降 2.26 个百分点。
以视频为单位进行配对重采样后,两种方法的准确率差值的等尾 95% 区间为 [-3.71, -0.80] 个百分点。

更详细的统计如下:

结果表明,notes 能够让一部分题由错变对,但让更多题由对变错,净减少 45 道正确回答。

答案格式#

两组采用同一解析规则 explicit_prefix_v1:可接受单字母或明确的 A. 文本、(A) 文本 等选项前缀;歧义或无法解析的输出计错。

思考#

本实验的 notes 组被 prompt 要求输出画面描述作为 note,但是这个过程没有提供已有 notes,从而降低 memory 的时间逻辑连续性,并且可能造成潜在冗余。

替代方案是让模型生成 notes 时额外提供已有 notes;此外,除了追加 note,还可以要求模型重写整个 memory,不过成本会更高。

此外,生成和使用 Memory Notes 的能力没有经过监督训练得到专门强化,因此模型很可能生成一段忠实的描述,但不一定在其中保留有利于后续判断的细节;时间戳信息也未必能被模型很好利用。

可以得出的结论是:在本文的数据、模型、提示词和预算下,直接添加分段文字记忆增加了写入成本,却没有带来准确率收益。
