@TaliaRinger What purpose would it even? How wouldn't we know that it isn't just pure nonsense?

@GaryMarcus @polynoamial For verifiable problems reducing the search space is in itself a great achievement. Obviously the false alarm rate was low enough for this result to be achieved practically.

@dileeplearning Thx! Our clones are effectively duplicated head direction cells, and cloned networks are designed to have the same ring manifold as classic models, so turns of 360-deg, 720-deg, etc bring network activity back to the same manifold location. Different flavor of clone than CSCGs :)

Story time friends... Ring attractor networks rely on fine-tuned symmetric connectivity. The fly head direction network has ring attractor dynamics but heterogeneous connectivity. How is this possible? 1/🧵 Link: biorxiv.org/content/10.648…

@BradKHulse interesting...have you checked whether the clones can represent the number of turns? ie. if you turn around 360 degrees once vs twice, does the activity among the clones change?

Thanks for reading, and huge shoutout to my wonderful coauthors and collaborators P.B. Aneesh, Sandro Romani, Vivek Jayaraman, and Ann Hermundstad!

@kareem_carr There was 0 human involvement. The prompt is in the report. The final answer by the model is in the report. And we have a (gpt-rewritten) CoT that we released.

@carlkolon No it isn’t. In fact evolution is an algorithm that seems to be bitter-lesson-pilled. I don’t think the bitter lesson essay addresses the question of data efficiency on the learning side and compute efficiency on the planning/inference side.

The entire NIH annual budget for neuroscience research - for all scientists across the entire US - is about $3bn a year. And now there are something like a dozen "neolabs" that have all raised O($1bn) within months of being founded, and they are all doing the same thing.

Sources: xAI co-founder Igor Babuschkin plans to raise up to $1B at an up to $5B valuation for a new AI research startup, with General Catalyst possibly leading (Forbes) (Visit Techmeme dot com for the link and full context!)

@dileeplearning show me where in the original question i asked whether it was an overbuild… (I do happen to think it is, but again not what was i asking)

Nope. This is wrong at many different levels. 1) Scaling is driven by real usage demand 2) Manhattan project and Apollo mission are wrong comparisons because they were research budgets, not serving users budget. 3) Internet based distribution is instantaneous. A single person cannot ride multiple rail cars at the same time. So their growth rates cannot be compared 4) no it doesn’t need to get to AGI for it to remain extremely useful.
Gary Marcus@GaryMarcus

Am I right that hyperscaling compute is the biggest bet in history? Any counter examples? It’s way more expensive than the Manhattan Project, the Apollo project, and railways across the US. If it doesn’t yield AGI, it may also be the biggest failed bet in history.

@GaryMarcus Sure all I am saying is the specific comparisons you had are not particularly meaningful in determining whether this is an over-building or not. The characteristics are very different.

i asked about the money invested, and only some of this (if any) is relevant. rather, most of it is an assessment of utility, which is not what I asked for. that said, with respect to utility, yes there is (some) utility (eg for programming) the question is whether the investments make sense economically. so far most of the major players aside from chip companies are spending far more than they are earning, which is not sustainable. the bet is about those economics and whether they will change. although you have some interesting things to say, i don’t think overall that they were responsive to what i asked.

This book -- Apprentices of Wonder -- is from 1989, reporting on the previous neural net era. It took 35 years after that, but anyone using coding agents should absolutely get the feeling of having apprentices of wonder!

The Silk Road made everyone rich, and then it killed half of them. Progress ep02 is live with @typesfast of @Flexport. We discuss why the global economy is as fragile as ever, what it takes for America to build again, and whether AI needs its own god.

In what is the hardest decision of my career, I’m moving on to a new chapter after nearly 8 incredible years at @GoogleDeepMind. I feel a profound sense of pride looking back at our work. From fundamental advances in RL and inverse RL to applications in robotics and science – navigating the planetary scale of Google Maps, reaching into space with LIGO, returning to planet Earth with language modelling, and finally pushing the physical boundaries in Gemini Robotics. The insights we gained, the systems we built, and the helping hand given to algorithms leaving the digital world for our physical one. Technology is only half the story. GDM creates a unique environment and – connecting Controls, Robotics, Maps, and Gemma teams – I feel privileged to have witnessed this paradigm shift together. I’ve never met a kinder or more driven group. To the brilliant people I've worked with: Thank you – I know you will continue to redefine AI. Why leave? The pull of a new frontier. Spending time at the intersection of digital and physical AI has made something clear: we are entering an era where AI’s physical proficiency is in reach. But we also need to be humble and reshape digital approaches to guide robotics onto the shoulders of its existing giants. The next chapter leans entirely into this and I’m looking forward to sharing more soon!

This is the strongest ephys evidence so far for a generative model in the brain that I know of. Congratulations @WadiaVarun! Wonderful collaboration with @UeliRutishauser on science that could only be done in humans. And please check out Fig. 5FG. This is new since biorxiv and really surprised me: the mean response to imagery and viewing is actually the same & there are many cells that respond only during imagery--challenging the idea that signal strength is what distinguishes reality from imagination.

1/8 Our preprint is now a peer-reviewed paper :) Big thanks to our reviewers who pushed us to examine our results more carefully and Olivier Wyart (headquarter.paris) for the exquisite visual. science.org/doi/10.1126/sc…
