一篇新的研究论文提出，扩散模型中的记忆现象并非全局属性，而是由局部数据覆盖决定的。该研究将扩散模型与核密度估计联系起来，推导出一个理论标准，该标准根据模型邻域中训练数据的密度和数据集的总体大小来预测记忆现象。该框架表明，数据覆盖率低的区域容易发生记忆现象，而密集区域则有利于泛化，这一现象已得到经验验证。 AI
影响 提供了扩散模型记忆现象的局部视角，根据数据几何解释其发生。
排序理由 该集群包含一篇在arXiv上发表的研究论文，详细介绍了关于扩散模型的理论和实证发现。

Memorization in diffusion models is often treated as a global property of the model or dataset. In practice, however, a single diffusion model can simultaneously generate both memorized and novel samples. Which training samples are most likely to be memorized? In this work, we sh…
