目前有很多种不同类型和应用的diffusion models。但在这篇文档中,我们将构建最基础的、无条件的diffusion model(unconditional diffusion model)-DDPM(Denoising Diffusion Probabilistic Models)[1]。我们首先探讨算法是如何工作的,然后再从零开始使用Pytorch来构建它。另外,这篇文档重点放在算法背后的想法和具体的实现细节。

最后,我们将讨论DDPM中用于图像生成的训练和推理,并在PyTorch中从头开始进行编码。 1. 生成模型的必要性 基于图像的生成模型的工作是生成相似的新图像,换句话说,是我们原始图像集的“代表”。 我们需要创建和训练生成模型,因为可以用(256x256x3)图像表示的所有可能图像的集合是巨大的。图像必须具有正确的像素值组合来...

most existing methods focus exclusively on bottom-up de novo design of compounds or tackle other drug development challenges with task-specific models. The latter requires curation of suitable datasets, careful engineering of the models and retraining from scratch for each task. Here we show how a...
