English(EN) Sidewalk Moments: Are Richer Representations Always More Human-Aligned? Evidence from City-Walk Videos

研究质疑更丰富的视频表征是否总是更符合人类

一项题为“Sidewalk Moments”的新研究调查了更丰富的视觉表征是否能带来更符合人类的城市参与度衡量标准。研究人员分析了 61 个城市步行视频,将其分割成片段,并使用时空视频特征、时间平均图像 (TAIs)、音频嵌入和文本描述进行表征。虽然视频特征在连续分析中显示出更强的对齐性,但在高参与度时刻的二元分类中,TAIs 的表现与完整视频片段相当或更好,这一点已通过在 Amazon Mechanical Turk 上进行的一项研究得到证实。研究结果表明,使用 TAI 的感知基础时间压缩可以作为一种可行的替代方案,用于测量符合人类的参与度。 AI

影响 挑战了更丰富的 AI 表征本身就更符合人类的假设,并提出了替代的压缩方法。
