TITLE
Semantically-correlated memories in a dense associative model

SPEAKER
Tom Burns (Cornell University)

ABSTRACT
I introduce a novel associative memory model named Correlated Dense Associative Memory (CD AM), which integrates both auto- and hetero-association in a unified framework for continuous-valued memory patterns. Employing an arbitrary graph structure to semantically link memory patterns, CDAM is theoretically a nd numerically analysed, revealing four distinct dynamical modes: auto-association, narrow hetero-a s association, wide hetero-association, and neutral quiescence. Drawing inspiration from inhibitory modulation studies, I employ anti-Hebbian learning rules to cont rol the range of hetero-association, extract multi-scale representations of community structures in graphs, and stabilise the recall of temporal sequences. Experimental demonstrations showcase CDAM’s efficacy in handling real-world data, replicating a classical neuroscience experiment, performing image retrieval, and simulating arbitrary finite automata .
