深层次原因:\alpha-cos \space noise \space schedule 本身是没有问题的,它的设计背景是Latent Diffusion Model, diffusion model 所作用的信号是低分辨率(32x32 或者 64x64)的,但是在Simple Diffusion的设计背景下,需要去掉VAE,直接在pixel space上做高分辨率的图像生成任务,这意味着在扩散过程中,信号会涉及到分辨...
A simple diffusion model in which the plane is treated through a diffusion coefficient for Coulomb multiple scattering lower than that of a random medium and blocking is depicted as a specular reflection from the plane, has been developed to explain the occurrence either of feeding-in or blocking...
Hi, I am trying to model the diffusion of a concentrated solution (source) through a porous 3-channel device. My right channel is my source channel, and my left channel is my sink channel. I am interested in the gradient of concentration developed in the middle channel after an hour, aft...

(iii) For [C.sub.2][H.sub.6], where the detection limit is only 5 ppm, a clear breakthrough curve was detected, but it could not be fitted by a simple diffusion model (see Figure 1): a quasi-stationary state is reached very soon, but after about 150-200 days, the outlet concen...
Diffusion Models 扩散模型是受非平衡热力学的启发。它们定义一个扩散步骤的马尔可夫链,逐渐向数据添加随机噪声,然后学习逆扩散过程,从噪声中构建所需的数据样本。与VAE或流动模型不同,扩散模型是用固定的程序学习的,而且隐变量具有高维度。 训练阶段,是在图片中添加噪声,给网络输入这一张添加噪声的图片,网络需要预测...
作者提出在Stable Diffusion Model的基础上添加设计的Adapter,只需要训练这些Adapter来完成迁移学习,大大减少了参数,而且可以取得惊人的效果 作者提出了两种Adapter,分别处理时间和空间信息,除此之外,作者海提出了Latent-Shift Attention Module,降低了处理时间信息的复杂度。 提出的Adapter可以应用到Video Super-Resolution和...
Simple Diffusion #1 deggers1 New Member Join Date: Jun 2009 Posts: 1 0 I am new to Fluent and need to model very simple 2D or 3D diffusion. Can anyone help me to simulate point source diffusion of a protein in a liquid in which I could view concentration contours at certain time inter...
“none” condition, the fits are much better than the regular UGM, and are equal to, if not better than, the diffusion. Although these the fits are about equally good for the diffusion model and the UGM with a free time constant, both models appear to misfit in quite different ways: ...
