这里的p(x~1:T|s1:T)被拆分为了多个概率的乘积形式,每一项p(x~t|x~t−L:t−1,st−L:t)都意味着当前帧的生成依赖于之前生成的L帧和源视频中t时间点及t之前的L帧(所以共计L+1帧)。L可以看成是窗口的长度(很明显,L≥1, 论文中使用L=2)虽然论文没有直接说,但t−L应为非负数。我们通过一...
此外,本文还提出了在推理阶段通过调整patch在网格中的排列来控制生成视频的尺寸的策略。 2.4 Scaling transformers for video generation 扩展变换器 Sora 是一种扩散模型。 该模型在接收到噪声patch和条件信息(如文本提示)后,能够预测出原始的“干净”补丁。值得一提的是,团队发现扩散变换器同样有效地扩展为视频模型。
