Uniform-based discrete diffusion models behave as associative memories that retrieve unseen data, with a dataset-size-driven memorization-to-generalization transition detectable via conditional entropy of token predictions.
Hierarchical Hopfield models retrieve concepts from noisy data via a strokes-concepts structure even without perfect stroke retrieval, as the second layer compensates for first-layer errors in both fixed- and variable-sized cases.
The paper reviews and extends energy-based dynamical models that use gradient flows and energy landscapes for neurocomputation, learning, and optimization tasks.
