zero-shotvideo captioning. 利用LLM模型来生成caption 利用caption进行数据增强 video captioner可以生成多个caption(比如20个),除了数据集中给定的query-video为正样本外,caption-video也可以作为正样本,为了避免生成的caption包含噪声,以至于caption完全和视频内容无关,作者通过使用预训练的文本编码器计算caption-query之间的...
Video-Caption交互:利用caption减少冗余特征,学习更具有判别性的视频表示,通过多种交互方法,如sum、MLP、Cross Transformer和Co-attention Transformer。Query-Caption辅助匹配:通过caption的全局特征与query匹配,提升整体匹配精度。实验分析不同的caption获取方法中,使用相似度最高的caption效果最佳。视频-字幕...
《Video-Text Modeling with Zero-Shot Transfer from Contrastive Captioners 》 arxiv链接:arxiv.org/pdf/2212.0497 摘要翻译: 这项工作探索了一种有效的方法,为包括开集视频分类(open-vocabulary video classification)、文本到视频检索、视频字幕生成和视频问答等任务建立一个基础的视频-文本模型。我们提出了VideoCoCa...

为了验证这个问题,作者将预训练CLIP的参数固定不动,使用纯文本的caption和hypothesis训练一个文本蕴含任务的分类器。接下来,对于图像-文本的蕴含任务,将图像侧信息输入到image encoder中,文本侧仍然输入到text encoder中,使用基于文本训练好的分类器进行预测。这样其实是只用文本蕴含任务的数据训练,得到了图文蕴含任务的...
