前言在Diffusion步数蒸馏的相关工作里,大家更加喜欢用分布匹配的概念,经典的工作比如SDS, VSD,Diff-Instruct,DMD,SiD, eta,而传统的像feature蒸馏那样去蒸馏output的做法逐渐被大家所抛弃,比如Progressive …
两者之间的差异代表着向着更加逼真且更少假象的方向,并将其反向传播给单步生成器。 Distribution Matching Distillation (DMD): DMD核心将预训练的扩散去噪器(diffusion denoiser)转化为快速的“一步”(one-step)图像生成器,同时保持生成图像的高质量。 预训练模型及一步模型生成器: 预训练基础模型(Pretrained base mod...
作者的推导使用扩散的均值预测形式来简化,但与-预测同样有效,仅需变量变换。作者的实现使用来自EDM和Stable Diffusion的预训练模型。 一步生成器() 的架构与基模型的扩散去噪器相同,但不包括时间条件。在训练前,一步生成器的参数 () 以基模型为初始化,即,。 分布匹配损失(Distribution Matching Loss) 理想情况下,...
作者期待通过蒸馏更先进的模型和引入变化的指导尺度,进一步提升模型性能和灵活性。 图1展现了一下和目前SOTA方法的对比: 基线稳定扩散(Stable Diffusion, SD):生成每张图像需要约250毫秒。扩散匹配蒸馏(Diffusion Matching Distillation, DMD):生成每张图像仅需约90毫秒。强调了DMD技术生成图像的速度比SD快得多,同时还在...
Combined with a simple regression loss to match the output of the multi-step diffusion model, our method outperforms all published few-step diffusion approaches, reaching 2.62 FID on ImageNet 64x64 and 11.49 FID on zero-shot COCO-30k, comparable to Stable Diffusion but orders of magnitude ...
To address this, we propose TSD-SR, a novel distillation framework specifically designed for real-world image super-resolution, aiming to construct an efficient and effective one-step model. We first introduce the Target Score Distillation, which leverages the priors of diffusion models and real ...

power distributionA new modified one-group diffusion scheme for one- and two-dimensional calculations of the gross power distribution in the BWR core is presented. The particularity of the present method is that the fine distribution of the ratio between thermal and fast neutron fluxes within each...
Actually, the short straight line represented Warburg impedance, caused by the ions diffusion at sensing material/electrode interface37. Therefore, the EC model shown in Fig. 4b3 was suitable for the sensing mechanism of Pyr-rGO at this stage. At high RH range, apart from the chemical ...
The one-dimensional structure shortens the path for lithium ion diffusion and electron transfer, and accommodates the large volume changes upon cycling. The introduction of rhombohedral corundunm-type In2O3 can favorably improve the electrical conductivity, provide more pathways for lithium ion ...
