显卡是NVIDIA RTX 3080 10G，生成模型统一采用Chilloutmix-Ni，采样步数(Sampling steps)一律设成30步，图片size设为800*800，并且不额外使用其它的ControlNet与Lora等影响生图速度的套件。仅单纯地用内建功能使用同一组prompt随机生图，一次生4张。并且生图过程中不会开启其它软件或对电脑做其余操作，以免影响生图速度。
除了LMS、DMP2 a 和PLMS在20步以下出现明显的瑕疵,其他的都很不错。 UniPC 的创意性更足,基本上5个step给了5个惊喜。 最常用的DPM++ SDE Karras,在20 step之后很稳定,构图基本没变化。 采样步数(Sampling steps) 一般采样步数选择20-50之间,也是视大模型而定。 但AI技术始终在进化,SD最新嵌入的UniPC采样器...

In the last few steps of sampling, you will find that this method deviates from the true region. You can verify this by plotting the image. So we only execute this method for half of the steps. You may question that if the trajectory of x is a concave function, this theory does not...

The arm is assumed to bend in a single plane, at an angle θb from a reference plane. The angle θb depends on the actuators selected and pressures applied. The derivation steps are to (1) establish kinematics, (2) determine reaction forces and (3) apply equilibrium relations. Download:...
Moreover, we propose a fast EM method via the exponential-sum-approximation technique to reduce the EM method's computational cost. More specifically, if one disregards the Monte Carlo sampling error, then the fast EM method reduces the computational cost fromO(N2)\\documentclass[12pt]{minimal...

The last step computes the cost functional for all NPC vectors and chooses the vector that gives the minimum cost functional value in that sampling interval. These three steps are repeated in the next sampling time. Predictive controllers for power electronic converters seem to be a potential ...
