English(EN) Intrinsic Temporal Adaptation of CLIP for Partially Relevant Video Retrieval

新框架通过时间自适应增强视频检索

作者 PulseAugur 编辑部 · [1 个来源] · 2026-09-07 04:00

研究人员开发了一个名为内在时间自适应（ITA）的新框架，以改进部分相关视频检索（PRVR）。该方法通过允许CLIP的视觉Transformer层处理相邻帧组来增强其时间理解能力，从而创建具有时间感知的嵌入。ITA还结合了亲和度加权梯度传播，以更好地处理PRVR的弱监督特性，有效地聚合和传播学习信号到相关帧。 AI

影响提高了文本查询的细粒度视频理解和检索准确性。

CLIP 的内在时间自适应用于部分相关视频检索

arXiv:2609.04800v1 Announce Type: new Abstract: Partially Relevant Video Retrieval (PRVR) aims to retrieve untrimmed videos that contain moments relevant to a text query. Since the target moment occupies only a portion of the video, PRVR requires retrieval based on fine-grained u…
