In our previous post, “Introduction to Diffusion Models for Image Generation”, we didn’t discuss the math behind these models. We provided only a c...
{daquanzhou, jshfeng}@bytedance.com, xinchao@nus.edu.sg Abstract Despite the recent visually-pleasing results achieved, the massive computational cost has been a long-standing flaw for diffusion probabilistic models (DPMs), which, in turn, greatly limits their applications on resource-limited plat...
首先我们根据 score-based DPMs 来推导如何利用额外的分类器来条件采样 [7]. 注意到 \[\begin{array}{ll} \nabla_{\bm{x}_t} \log p(\bm{x}_t|y) &=\nabla_{\bm{x}_t} \log \frac{p(\bm{x}_t) p(y|\bm{x}_t))}{p(y)}\\ &=\underbrace{\nabla_{\bm{x}_t} \log p(\bm...
Diffusion probabilistic models (DPMs) have achieved impressive results in high-resolution image synthesis. A technique called guidance sampling is used to improve the sample quality of DPMs. The denoising diffusion implicit model (DDIM) is a common...
Diffusion probabilistic models (DPMs) are a new class of generative models that have achieved state-of-the-art generation quality in various domains. Despite the promise, one major drawback of DPMs is the slow generation speed due to the large number of neural network evaluations required in the...
9、DPM-OT: A New Diffusion Probabilistic Model Based on Optimal Transport 从扩散概率模型(DPMs)中进行采样可以看作是一个分段分布转换,通常需要反扩散轨迹的几百或几千步才能得到高质量的图像。最近在设计DPMs的快速采样器方面取得的进展通过知识蒸馏或调整方差计划或去噪方程的方式在采样速度和样本质量之间取得了...
Diffusion probabilistic models (DPMs) haveshown remarkable performance in visual synthesis but are computationally expensive due to the need for multiple evaluations duringthe sampling. Recent predictor-corrector diffusion samplershave significantly reduced the required number of function evaluations (NFE), ...
Diffusion probabilistic models (DPMs) have achieved impressive success in high-resolution image synthesis, especially in recent large-scale text-to-image generation applications. An essential technique for improving the sample quality of DPMs is guided sampling, which usually needs a large guidance scale...
