Attention over noisy examples: generalization and memorization in the exponential Hopfield network

arXiv:2610. 22191v1 Announce Type: cross Abstract: In Hebbian learning from examples a Hopfield network of $N$ neurons is not supplied with the $K$ archetypes it has to retrieve but with $M$ blurred examples of each, of quality $r$, and whether it can infer them depends on the load $\alpha=K/N$ (interference among them) and on the dataset entropy $\rho=(1-r^2)/(Mr^2)$ (how little the examples say about them).

Sliding Networks: A Family of Residual Structures Preserving Feature Learning and Feature Diversity

The paper introduces Sliding Networks, a family of residual neural network structures that aim to preserve both feature learning and feature diversity while scaling width and depth. By maintaining a limiting ratio of residual width to the product of hidden width and depth, the authors derive a joint scaling recipe that converges to a stochastic differential equation (SDE) limit with locally maximal feature learning. Experiments on residual-MLP and language models demonstrate that this scaling approach allows redistribution of computational resources between width and depth, though performance varies when parameters are regrouped at a fixed count.
