SGF+：解耦自回归视频生成的梯度流

arXiv 2610.10429 · 22 人推荐 · 附代码 Zihan-Su/Self_Gradient_Forcing_Plus。Autoregressive video generation requires denoising the current frames while writing their key-value representations as context for future predictions. However, these two roles typically share parameters, and we find that their gradients exhibit distinct patterns and systematic negative alignment, hindering the joint optimization of visual quality and temporal consistency. We introduce Self Gradient Forcing Plus (SGF+), which assigns separate parameters to context writing and denoising while pres
