English(EN) LinMorph: Learning to Morph Weights for Efficient Video DiT Linearization

LinMorph 方法学习权重变换以实现高效的视频 DiT 线性化

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-15 04:00

研究人员开发了 LinMorph，一种用于高效线性化预训练视频扩散 Transformer (Video DiT) 的新颖方法。与之前专注于注意力替换后恢复质量的方法不同，LinMorph 解决了初始化的关键瓶颈。它学习跨参数变形来转换 softmax 到线性的权重，使目标门控 DeltaNet (GDN) 参数能够从多个预训练投影中提取。与随机初始化或启发式权重重用相比，该技术能够实现更快的恢复和更好的生成质量，并且可以在短视频片段上学习，以便在更大的视频规模上重用。 AI

影响这项研究可能导致更高效的视频生成模型的训练和部署。

LinMorph：学习模型权重以实现高效视频DiT线性化

arXiv:2610.17914v1 Announce Type: cross Abstract: Post-hoc linearization is an attractive way to accelerate pretrained Video Diffusion Transformers (Video DiTs), yet existing methods largely treat the quality loss induced by attention replacement as a recovery problem. We show th…
