扩散模型蒸馏在高维空间中表现出“复制”行为

作者 PulseAugur 编辑部 · [2 个来源] · 2026-06-01 13:30

研究人员在扩散模型的高维蒸馏中发现了一种称为“复制”的现象。当蒸馏出的学生模型复制教师模型的原始噪声-数据配对时，就会发生这种情况，而在低维设置中并未观察到这种行为。研究表明，这种复制是由于学生模型在蒸馏过程中几何自由度有限而产生的涌现特性，而不是对抗性目标或教师记忆所致。 AI

影响识别出扩散模型蒸馏中的一种新行为，可能影响压缩模型的效率和泛化能力。

Why Are DMD Students Lazy? Understanding the Copying Behavior in Few-Step Distillation

Distribution Matching Distillation (DMD) compresses pretrained diffusion models into efficient few-step generators by aligning their noised distributions across all scales. In principle, such distribution-level supervision remains agnostic to specific noise-data pairings of the t…
