English(EN) PixelU: A U-Shaped Transformer for Efficient End-to-End Pixel Diffusion

PixelU Transformer 提供高效的端到端像素扩散

作者 PulseAugur 编辑部 · [2 个来源] ·

研究人员推出 PixelU，这是一种新颖的 U 型扩散 Transformer，专为高效的端到端像素扩散而设计。该模型通过关注 $x$-预测范式而非 $v$-预测，挑战了像素空间扩散中复杂解码器的必要性。PixelU 利用零成本跳跃连接直接路由高频细节，并采用恒定通道空间下采样机制来分离低频语义。在 ImageNet 上的实验表明，PixelU 在计算成本显著降低的情况下，取得了与现有方法相比具有竞争力的 FID 分数。 AI

影响 引入了一种计算效率更高的像素扩散模型方法，有可能加速生成图像合成领域的研究和开发。
