1. Attention over noisy examples: generalization and memorization in the exponential Hopfield network
   Source: cond-mat.dis-nn (Disordered Systems and Neural Networks)
   Link: https://arxiv.org/abs/2610.22191
   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).
