采样步数与采样器 在 Stable Diffusion 中，采样步数与采样器之间存在一定的关系。采样器是指用于生成随机高斯噪声的设备或算法，它直接影响着采样步骤中的噪声水平。不同的采样器可能会需要不同的采样步数来达到相同的降噪效果。因此，在选择采样步数时，我们需要综合考虑采样器的性能以及所需的降噪程度，以达到最佳的...
在计算机图形学中,Sampling Steps(采样步长)是指在绘制图像或渲染图像时,在像素级别上进行采样的间距。采样步长的选择直接影响到图像的细节和质量。 采样步长的大小决定了图像中每个像素的采样点数量。如果采样步长较小,即采样点较多,可以获得更高的细节和精度,但同时也会增加计算量和渲染时间。如果采样步长较大,即采...

However, for latent-space diffusion models (such as stable-diffusion), the thresholding method is unsuitable because the x 0 at time 0 of the diffusion model is in fact the "latent variable" in the latent space and it is unbounded. Comparing singlestep or multistep methods. Comparing order ...

In both ADM and Stable Diffusion, PAG surprisingly improves sample quality in conditional and even unconditional generation. Moreover, PAG significantly enhances baseline performance in various downstream tasks where existing guidance methods such as CG or CFG cannot be fully utilized, including Control...
The proof is given in Methods C. By recasting this theorem in terms of q-samples and by further loosening Eq. (6) we obtain the following corollary: Corollary 1 Consider a q-sample \(\left\vert P\right\rangle\) for which the iMPS representation has d ≥ 3 non-zero Schmidt coeffi...
By training the network q(x|w) to minimize the loss l(w|θ), we obtain a maximum likelihood estimate of the committor5 that is differentiable and enables sophisticated analysis methods16. We then use symbolic regression17 to condense the molecular mechanism into a human-interpretable form (Fig...
