生成的样本的质量要高 high-quality sampling. 模态覆盖率要高/多样性 mode coverage/diversity. 快速高效的采样 fast and computational inexpensive sampling. 为了能在数据的边缘分布不是高斯分布的情况下, 也能减少采样的步数, 这种情况下既然真实的去噪过程的分布不再服从高斯分布的形式, 那么将反向过程的分布也不...
Inspired by the recent efforts that leverage diffusion recovery likelihood learning as a cure for the sampling issue, we introduce a novel symbiosis between the diffusion models and latent space EBMs in a variational learning framework, coined as the latent diffusion energy-based model. We develop ...

We fix a common setup for all the experiments: the denoiser model is defined as a U-Net model with four down/up sampling stages and attention only at the bottleneck level in order to reduce the memory footprint. In total, the model has around 50 million parameters, which is a small num...

Sampling Steps(采样步数)Stable Diffusion 的工作方式是从以随机高斯噪声起步,向符合提示的图像一步步降噪接近。随着步数增多,可以得到对目标更小、更精确的图像。但增加步数也会增加生成图像所需的时间。增加步数的边际收益递减,取决于采样器。一般开到 20~30。
