针对diffusion ODE的最大似然训练问题一直是个open problem,我们发表在ICML 2022的Maximum Likelihood Training for Score-Based Diffusion ODEs by High-Order Denoising Score Matching从理论角度彻底解决了这个open problem。我们的理论贡献可以浓缩为一个图: Diffusion SDE与Diffusion ODE的联系与区别 这里面涉及到的公式...
3. 还是因为diffusion model和score的联系，它可以用来做inverse problem solver的learned prior（例如我有...
New diffusion models are proposed for the OBIM problem, which are the One-time impression (OI) model [34], Multi-time impression (MI) model [35] and Logistic influence (LI) model [36]. • One-time impression (OI) model. [34] presented the OI models, which specify that given a ...
之后就是2021年很多方法【6-8】在DDPM上改进(加快采样,UNet改进结构等)。 (根据这篇文章[1],Yang Song是在不知道【1】Diffusion-Original 成果的情况下想出的NCSN,【1】估计分布,【2】NCSN估计score。【1】Diffusion-Original 在15年各种比不上GAN,是【2】NCSN和【4】DDPM做出了现代版的diffusion model。)...

The issue has not been reported before recently The issue has been reported before but has not been fixed yet What happened? No model is showing after i press refresh and no settings is seemingly saved, they all show error. Steps to reproduce the problem ...
Is there an existing issue for this? I have searched the existing issues and checked the recent builds/commits What happened? 启动webui后无法生成图像 Steps to reproduce the problem 1.启动webui 2. 输入提示词 3.开始生成图片 What should have happened? 正常
Checkpoint model是对Stable diffusion模型更精确的称呼。它用于区分LoRA、textual inversion和Lycoris。 ComfyUI ComfyUI 是基于节点的用户界面,由 Stable Diffusion 开发。它深受高级 Stable Diffusion 用户的喜爱。 ControlNet ControlNet是一个神经网络,通过引入额外的条件来控制图像的生成过程。
）。从这个角度说，diffusion model是有缺陷的，因为它的泛化性其实是模型设计的结果而非理论推导的结果...
