Researchers show fact-storing MLPs can be viewed as Hebbian memories

A research thread argues that fact-storing MLPs can be understood as Hebbian memories: keys and queries are mapped into a higher-dimensional feature space, giving a cleaner construction and optimal storage scaling.
The diagram contrasts a plain MLP with a Transformer block and highlights that this view explains how memories can be stored and later used by Transformers, with storage capacity scaling as |W| = F log(F).
