根据文本生成图片是AI的核心应用之一,2020年后主流的生成方式都是基于Denoising Diffusion Probabilistic Models原理的,逐渐替代了之前使用GAN的方式生成图片!那么DDPM为啥能取代GAN了?其优势在哪?或者说GAN的劣势在哪? 1、CLIP模型都知道吧? text和image都通过各自的encoder转成embedding,然后两个embedding计算cosin距离,距...
Traditional approaches, including computationally-demanding regional dynamical models or statistical downscaling frameworks, are often susceptible to the influence of downscaling uncertainty. Here, we address these limitations by introducing a diffusion probabilistic downscaling model (DPDM) into the meteorological...

Diffusion probabilistic models (DPMs) have emerged as a promising technique in generative modeling. The success of DPMs relies on two ingredients: time reversal of diffusion processes and score matching. Most existing works implicitly assume that score matching is close to perfect, while this ...
