新研究通过新颖的采样策略改进扩散模型训练

作者 PulseAugur 编辑部 · [1 个来源] · 2026-08-31 04:00

一篇新研究论文探讨了训练扩散模型从由非归一化密度或能量函数定义的分布中采样的各种方法。该研究对现有的基于仿真的变分和离策略生成流网络方法进行了基准测试，并对一些先前的说法提出了质疑。它还引入了一种新颖的离策略方法探索策略，利用局部搜索和回放缓冲区来提高各种目标分布的样本质量。作者已公开了他们用于这些采样方法和基准测试的代码，以促进扩散模型在摊销推理方面的未来研究。 AI

影响引入了一种新的采样策略，可以提高扩散模型在各种应用中输出的效率和质量。

改进的扩散采样器离策略训练

arXiv:2402.05098v5 Announce Type: replace-cross Abstract: We study the problem of training diffusion models to sample from a distribution with a given unnormalized density or energy function. We benchmark several diffusion-structured inference methods, including simulation-based …
