2022年9月3日 · Technical details regarding Stable Diffusion samplers, confirmed by Katherine: - DDIM and PLMS are originally the Latent Diffusion repo DDIM was implemented by CompVis group and was default (slightly different update rule than the samplers below, eqn 15 in DDIM paper is the update rule vs solving eqn 14's ODE directly)

2022年8月29日 · k_lms is a diffusion-based sampling method that is designed to handle large datasets efficiently. k_dpm_2_a and k_dpm_2 are sampling methods that use a diffusion process to model the relationship between pixels in an image. k_euler_a and k_euler use an Euler discretization method to approximate the solution to a differential equation that ...

In the context of Stable Diffusion, converging means that the model is gradually approaching a stable state. This means that the model is no longer changing significantly, and the generated images are becoming more realistic. There are a few different ways to measure convergence in Stable Diffusion. One common way is to use the loss function.

2022年11月18日 · While some samplers out performed Euler a in some categories, if you are looking for a good sampling method that does well all around, you cant go wrong with Euler a. Also another thing I found interesting is that while you don't need to go above step 30 with Euler a most of the time, the quality of generated images peaks at 50 steps.

Apparently a "Pseudo-Numerical methods for Diffusion Models" version of LMS. DDIM. Denoising Diffusion Implicit Models. One of the "original" samplers that came with Stable Diffusion. Requires a large number of steps compared to more recent …

2022年12月9日 · CFG Scale, one of the sliders in Automatic1111's WebUI. I think it's the --scale parameter if you use the stable diffusion command prompt, but I'm not entirely sure since I haven't used Stable Diffusion without an UI for a while now.

2022年11月6日 · Then you need to restarted Stable Diffusion. After this procedure, an update took place, where DPM ++ 2M Karras sampler appeared. But you may need to restart Stable Diffusion 2 times. My update got a little stuck on the first try. I saw about the fact that you sometimes need to remove Config in a video tutorial.

DPM++ 2M I tried many, had favorites among them for some time, but I went back to that one. I use it most of the time now, but like you said yourself, some models work better with some schedulers, so I sometimes have to revert to those.

2022年10月10日 · Also for whatever reason some methods give pretty much the same result for a given prompt + seed, with varying degrees of differences in detail, which others just go with completely different image. I honestly don't know the point of adding more methods, besides giving more tools to explore the same seed with an identical prompt.

2022年11月21日 · Whats the best sampling method for anime style faces? I want some that look strait out of stuff like Fate/Stay Night but I also want to get some that resemble Sakimichan, Alexander Dinh, Axsen, and Personalami's art styles.
