SparSTAR 通过稀疏注意力提高了视频合成效率

研究人员开发了 SparSTAR,一种用于稀疏注意力的创新方法,旨在提高 InfinityStar 等自回归视频合成模型的效率。SparSTAR 通过选择性地计算注意力块来解决视频生成中不同尺度和跨剪辑上下文相关的计算成本问题。该方法在保持视频合成任务高保真度的同时,提供了约 1.6 倍的显著加速。 AI

影响 SparSTAR 的效率提升可能会加速高分辨率自回归视频合成模型的开发和部署。

    SparSTAR:用于时空自回归视频合成的稀疏注意力

    InfinityStar extends visual autoregressive generation to video through a sequence of image and clip pyramids. Its changing scale and cross-clip context, however, leave late-scale attention costly and make sparse patterns reused from diffusion or image VAR models unreliable. We in…
