3.2、classifier-free guidance 在classifier-free guidance model 中,没有利用 classifier,而是同时训练了condition model 和 unconditional model,而且使用同一个网络来实现,只需要需要输入信息中的类别信息即可,在生成过程中,则通过调整两种模型的 score 的权重来在多样性(FID)和真实度(IS)中权衡取舍。 3.2.1 训练 ...

To effectively handle the intricate challenges of RISR, we adapt classifier-free guidance (CFG), a technique initially developed for multi-class image generation. Our proposed method, Real-SRGD (Real-world image Super-Resolution with classifier-free Guided Diffusion), decomposes RISR challenges into...
第3 篇:《Diffusion Models Beat GANs on Image Synthesis》 1、摘要 目前生成模型有好几种,包括 GANs 和 likelihood-based models 等,目前在生成任务上,依然是 GANs 取得最好的效果,但 GANs 难以训练和扩展,限制了其应用。虽然 diffusion model 近几年有了大的发展,但在生成任务上,比较 GANs 还是略逊一筹。

Classifier-free Diffusion Guidance Diffusion models have recently emerged as an expressive and flexible family of generative models. Classifier_Free_DDIM_Mnist.ipynb is simple implementation of a conditional diffusion model, which is capable to generate MNIST digits. The model use the classifier-free g...
