2021年1月12日 · Denoising diffusion probabilistic models (DDPMs) have achieved high quality image generation without adversarial training, yet they require simulating a Markov chain for many steps in order to...

2023年2月1日 · Abstract: Our goal is to extend the denoising diffusion implicit model (DDIM) to general diffusion models~ (DMs) besides isotropic diffusions. Instead of constructing a non-Markov noising process as in the original DDIM, we examine the mechanism of DDIM from a numerical perspective.

2024年3月13日 · Welcome to the unofficial ComfyUI subreddit. Please share your tips, tricks, and workflows for using this software to create your AI art. Please keep posted images SFW. And above all, BE NICE. A lot of people are just discovering this technology, and want to show off what they created. Belittling their efforts will get you banned. Also, if this is new and exciting to …

Got very good results using DDIM, DPM++ SDE Karras, Euler Ancestral (apparently hated for inefficiency, but it works!). PLMS is the worst with the most distorted results.

2022年9月11日 · Has to do with how diffusion-based models work. Basically, they start with a random noise image and 'mine' the noisy image for a less noisy output. This process is defined by a differential equation that describes how much noise is removed in a step. Solving these equations is a bit tricky; there's different approaches with tradeoffs between speed and …

2023年3月5日 · Curious if anyone see any use for the other 10 or so samplers available on SD. Are there scenarios you'd use one over the others? For the triad (ddim, dpm, euler) - are there situations where you prefer one over the other?

2018年10月5日 · “Wn i ddim” comes from the more formal way of saying “I know”: “Gwn i”. You might see this in books, poems and songs and other places where you come across formal Welsh. As well as being formal, “Gwn i” is also used in a number of set expressions like “Wn i ddim” (I don’t know). Others include: “hyd y gwn i” (as far as ...

2022年8月24日 · I run a generation with [prompt] --n_sample 1 --n_iter 5 --dim_steps 50 I get 5 images. Then I run the same generation again, same EVERYTHING except --ddim_steps 150. I get 5 more images. The first image is identical to the one in the first run (slightly more detailed), but the rest are COMPLETELY different. I run the same generation with --ddim_Steps 10. Five …

2022年12月9日 · Honestly I feel the step count/cfg scale and other factors can have a unique effect (or not) on the generated image. A lot of the same parameters aren’t going to have the same effect, just like with Disco. You will hear that that only X amount of steps are needed for cohesion with sampler x. While this information is useful, it does take some tweaking and …
