arXiv:2607. 19195v1 Announce Type: cross Abstract: Using large deviations theory, we solve and obtain a general expression for the free energy functional for a broad class of associative memories, including dense associative memories.

The paper argues that diffusion models, originally developed for image synthesis, implicitly perform concept formation similar to the Cobweb cognitive model. Both models build hierarchical density structures using Gaussian prototypes, treat categorization as score‑following to reduce uncertainty, and exhibit a basic level of abstraction. The authors demonstrate this correspondence by extracting a diffusion hierarchy from MNIST and Fashion‑MNIST data and comparing its basic level to that of Cobweb, suggesting diffusion models can serve as a continuous, scalable instantiation of concept formation.

The paper investigates when language diffusion models, specifically Uniform-based Discrete Diffusion Models (UDDMs), shift from memorizing training data to generalizing to new data. It shows that UDDMs act as associative memories, forming basins of attraction around stored examples without requiring an explicit energy function. By measuring token recovery and conditional entropy, the authors identify a sharp transition governed by training set size, where memorization (vanishing entropy) gives way to generalization (finite entropy).

arXiv:2512. 14338v3 Announce Type: replace Abstract: Many learning problems involve symmetries, and while invariance can be built into neural architectures, it can also emerge implicitly when training on group-structured data.

arXiv:2605. 00366v4 Announce Type: replace-cross Abstract: High-capacity associative memories based on Kernel Logistic Regression (KLR) exhibit strong storage capabilities, but the dynamical and geometric mechanisms underlying their stability remain poorly understood.
