Paper analyzes generative models' memorization vs. generalization

A new paper analyzes generative models, questioning whether they truly learn data distributions or merely memorize training sets. Researchers found that diffusion models trained on separate data subsets converge to similar densities when the training data is extensive. The study analytically characterizes this transition from memorization to generalization in linear models, noting that convergence is continuous and occurs when sample size scales with input dimension, while recovery of latent factors happens abruptly.

    Memorisation, convergence and generalisation in generative models

    arXiv:2605.21402v1 Announce Type: new Abstract: Generative neural networks learn how to produce highly realistic images from a large, but finite number of examples - or do they simply memorise their training set? To settle this question, Kadkhodaie, Guth, Simoncelli and Mallat (I…
