This arXiv preprint offers a theoretical account of how diffusion models can memorize individual training samples instead of learning the underlying data distribution, and proposes a criterion meant to flag that failure. Its claims rest on analytical characterization and experiments across architectures designed to both promote and suppress memorization, so the practical value depends on how well the criterion holds up outside those settings. Readers working on generative model evaluation, privacy, or training diagnostics should check whether the detector transfers to larger, production-scale models.
Detection of Memorization in Diffusion Models Through Thermodynamic Singularity
arXiv:2610.27754v1 Announce Type: new Abstract: In diffusion models, proper distributional learning entails reversing a diffusion process over underlying density functions, whereas a key failure is memorization, in which the reverse process instead learns diffusion from individual training samples. We provide an analytical characterization of such memorized reverse processes, along with a criterion that detects the associated thermodynamic singularity. The proposed criterion reliably distinguishes between properly learned and memorizing networks across a range of neural network models designed to promote or mitigate memorization.
