I am really proud that eLife have published this paper. It is a very nice paper, but you need to also read the reviews to understand why! 1/n

TIL what the manifold hypothesis is. I'd imagined it was that neural activity can be described using manifolds 😅 which should be true since a manifold is what one does calculus on 😁
'"This dimensionality is (...) much smaller than the full population space." - literally the manifold hypothesis'
'"This dimensionality is (...) much smaller than the full population space." - literally the manifold hypothesis'
Y’all are reading this paper in the wrong way.
We love to trash dominant hypothesis, but we need to look for evidence against the manifold hypothesis elsewhere:
This elegant work doesn't show neural dynamics are high D, nor that we should stop using PCA
It’s quite the opposite!

“Our findings challenge the conventional focus on low-dimensional coding subspaces as a sufficient framework for understanding neural computations, demonstrating that dimensions previously considered task-irrelevant and accounting for little variance can have a critical role in driving behavior.”

We are remarkably good at recognizing natural auditory “textures”, such as the soothing sound of a running brook or fire crackling in a chimney. But do you think you could remember the exact rain texture that opens “Riders on the Storm”?

About "PhD-level AI". This is such a misunderstanding of scientific work. What a PhD is about is not technical skills or encyclopedic knowledge. It's about learning to prove (or disprove) claims. At core, it's the development of an ethical attitude to knowledge. Exactly what an LLM cannot provide.
