we demonstrate that previous high-order fast samplers suffer from instability issues, and they even become slower than DDIM when the guidance scale grows large. To further speed up guided sampling, we propose DPM-Solver++, a high-order solver for the guided sampling of DPMs. DPM-Solver++ solve...
例如,下图展示了不同采样算法在 Stable-Diffusion 上随着步数变化的效果,可见 DPM-Solver 在 10 到 15 步就可以获得非常高质量的采样: 使用DPM-Solver DPM-Solver 的使用非常简单,既可以基于作者提供的官方代码,也可以使用主流的 Diffusers 库。例如,基于作者提供的官方代码(https://github.com/LuChengTHU/dpm-sol...

I am using segregated solver and coupled dpm calculation with stochastic particle track. The calculation for the continuous phase converges without particle. The drop 23、diameter is 1.2 mm. Do you provide enough information? Best regards, You Can it have something to do with how often you ...
mine plan optimization.This paper presents a preliminary study that proposes the use of a hybrid solver for analyzing diesel particulate matter (DPM) in underground mines. The hybrid solver is based on a methodology that integrates two conventional techniques: a network solver and a computational ...
deep-floyd/IF#38 The cosine noise schedule has numerical issues for t near to 1000. We can just clip the lambda(t) to make dpm-solver suitable for cosine schedules (which does not affect other nois...
To mitigate this problem we provide the DPM with an efficient nonlinear activation-free (NAF) network and we employ as a sampler a fast solver of ordinary differential equations, which can converge in a few iterations. To better preserve text characters, we introduce an additional differentiable ...
As far as I know DPMFoam uses the same lagrangian classes as everything else, the DPM particulars come in higher up on the solver solver with Uc, volFraction sources etc... I'm not sure where the actually K is calculated from but I'm guessing its somewhere in the only p...
For the sampling strategy, we employ a fast solver of ordinary differential equations, which is able to converge in 20 iterations at most. The combination of a small number of parameters (only 9.4M), an efficient network and a fast sampling strategy allow us to achieve competitive inference ...
