Researchers have developed new methods for detecting memorization in diffusion models, a phenomenon where the models reproduce training data examples. The proposed techniques combine split conformal calibration with sequential monitoring to adaptively detect memorization across different timesteps in the denoising process. Experiments on a CIFAR-10 diffusion model demonstrated that sequential monitoring improves the power-timing tradeoff compared to fixed-time detection, with trajectory-level calibration enabling earlier detection than Bonferroni calibration.
