Great summary, thanks for writing this! One nit, we started the 'core' merely as a shared feature space for (translation invariant) visual neurons*. Simple idea, not to be conflated with all the 'foundation model' and 'digital twin' marketing later 😜 * proceedings.neurips.cc/paper/2017/f...

So I get that a Neuroscientist Couldn’t Understand a Microprocessor, and TBH I’m ok with that. But could a neuroscientist understand a deep RNN? Because that seems like a more pressing issue. *assuming you think the brain operates through the parallel activity of many connected input/output units

A study led by Cina Aghamohammadi is now out in ‪@natcomms.nature.com‬! We developed a mathematical framework for partitioning spiking variability, which revealed that spiking irregularity is nearly invariant for each neuron and decreases along the cortical hierarchy. www.nature.com/articles/s41...

Superposition has reshaped interpretability research. In our @unireps.bsky.social paper led by @andre-longon.bsky.social we show it also matters for measuring alignment! Two systems can represent the same features yet appear misaligned if those features are mixed differently across neurons.

➕ Bonus: Theory can explain the “Platonic Representation Hypothesis”—the striking observation that different models often learn the same representations. arxiv.org/abs/2405.07987 With the right assumptions (hopefully not too 🧚‍♀️), you get a rigorous mathematical explanation for why this happens 🤓

So—does this mean theory is doomed, and AI engineering is just a random walk? Not at all! 💡 @rpatrik96.bsky.social @wielandbrendel.bsky.social Randall Balestriero did an amazing job clarifying where theory can help practice—and where practice should inspire theory. 🤝

This all started last year with a simple question: who first applied sparse coding to neural representations for more interpretable codes? That question led us to uncover links between identifiability, compressed sensing, and interpretability—a story that was too good not to tell. 🧩

Defunding academic sciences while teaming up with big tech companies seems also like a great strategy to make sure they have a monopoly on research and, ultimately, its monetisation. If NSF stops funding academic AI research, then we can only *hope* OpenAI et al will work for the good of humanity 😳
