AI总结 提出结合共形预测与协同过滤式标注者表征的框架,通过幽灵预测度量和幽灵标注者表征量化模型预测与所有人类标注的分歧,并发现模型在标注者分歧时不确定性增加,但大型模型对无人类对齐文本更自信,且存在结构性人口统计偏差。

Comments The publishing of this preprint is contextual with the ACL ARR cycle system. After an encouraging review in January we revised and submit the paper on Arxiv. However, a new batch of reviewers raised additional issues that will lead to significant revisions of the experimental setting. Therefore, we decide to withdraw the manuscript

Track and Caption Any Motion: Open-Vocabulary Spatiotemporal Captioning via Trajectory-Conditioned Generation

跟踪并描述任何运动:通过轨迹条件生成实现开放词汇时空字幕

Bishoy Galoaa, Sarah Ostadabbas

机构 * Northeastern University(东北大学)

AI总结 研究提出TCAM框架,无需文本查询和区域提示,通过字幕感知重采样器在点粒度结合跟踪与语言,用现有分割注释训练,能描述视频中运动、定位时间及轨迹,优于密集视频字幕基线,匹配相关方法,为运动驱动视频理解提供新途径。
