新的 JAx 方法通过对齐预测来加速扩散模型训练

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-02 04:00

研究人员推出了一种新颖的扩散模型预测监督方法 JAx（Just Align x），该方法可以对齐不同噪声水平下的干净图像预测。与表示对齐不同，JAx 专注于改进预测目标本身，从而实现更稳定和加速的训练。该方法在 ImageNet 256x256 的各种 JiT 配置上，在 Fréchet inception distance (FID) 和收敛速度方面均表现出一致的改进，且无需架构更改或外部编码器。 AI

影响 JAx 为表示对齐提供了一种原则性的替代方案，有望提高生成模型的训练效率和性能。

仅对齐 $\bm{x}$：对齐预测而非表征

arXiv:2610.00600v1 Announce Type: new Abstract: Representation alignment has become an effective way to accelerate diffusion training, but its benefits do not transfer reliably to pixel-space clean-image prediction. In JiT, we find that auxiliary feature alignment can improve acc…
