Dense Associative Memories, aka modern Hopfield networks, have a huge memory storage capacity. But are they biologically realistic? In our new paper with @DimaKrotov we argue that they can be written in terms of biological variables. https://t.co/w58EAQ54xm

I very much enjoyed reading the papers from the first iteration of this workshop in 2023. If you are working on associative memory, consider submitting your work and participating in this event.

I am super excited to announce the call for papers for the New Frontiers in Associative Memories workshop at ICLR 2025. New architectures and algorithms, memory-augmented LLMs, energy-based models, Hopfield networks, associative memory and diffusion, and many other exciting

This award is very hard to respond to. I have received many hundred congratulatory notes, from former students, post-docs, Princeton University juniors and seniors, funding agencies and foundations, authors, signature collectors, amateurs, elementary school neural network

I was welcome in this group because I knew so little about conventional neuroscience that my questions threatened no one.

Their scientific interaction at small meetings of the Associates was intended to usefully drive the science. Alas, this meeting was more of the prima-donna behavior of a set of scientific leaders, rather than a coherent chorus, which frustrated Frank Schmitt.

Francis 'Frank' Schmitt already had an amazing view in 1962 of where neuroscience needed to go if you were serious about understanding higher brain function. His Neuroscience Research Program had a set of Associates spread across the relevant fields.

@TonyZador @suzanahh Yes! And some exciting things emerged out of the multidisciplinary meetings Schmidt organized on this topic - like @HopfieldJohn ’s inspiration to create Hopfield networks.

The mathematical idea that makes this possible is the Lagrangian for the dynamical system. This system can be turned into a multi-layer network with simultaneous forward and feedback flow of information.

Everybody knows about Lyapunov functions in simple networks with local non-linearities. What this paper shows is that with symmetric feedback a Lyapunov function can be constructed for arbitrary non-linear activation functions involving groups of neurons.

One of the great features of deep learning is that we can easily stack multiple layers (e.g. dense, conv, attention) with arbitrary activation functions to build a useful feedforward network. Wouldn’t it be cool if we could do the same for Modern Hopfield Networks with feedback?

New microscopic theory of Dense Associative Memory aka modern Hopfield network can be reduced to the model proposed in “Hopfield Networks is All You Need’’ paper, which is equivalent to self-attention mechanism of Transformers. Work with @HopfieldJohn https://t.co/jYAxIjvgKf

Several people asked me today about Dense Associative Memories and Hopfield networks. In this talk from 2018 I explain some of the intuition behind them. Apologies that the camera does not focus on the slides. Talk: https://t.co/GeBQjsn95h Slides: https://t.co/0Otb4dGbpP
