This is a great piece by Bill Bialek. arxiv.org/abs/2611.14381 He is an excellent and engaging writer. I wish though for a field where more people without his level of standing or privilege could feel free to write science in their own voice with more freedom of style beyond t…

AI Weekly's analysis →
  • William Bialek argues optimization can be promoted to a principle from which neural function and mechanism are derived, ideally with no free parameters.
  • The paper's headline claim: optimal performance need not require the underlying mechanisms to have finely tuned parameters, contrary to widely held intuitions.
  • The piece revisits diffraction-limited optics in insect eyes and recent theory on optimal motion estimation in fly vision as its anchoring cases.

"AI for mathematics...beyond all reasonable doubt the field is undergoing a rapid transformation, unlike anything that we have ever seen...Language models are solving hard problems which humans could not, and mathematicians are reacting very differently" xenaproject.wordpress.…

The EuroNMC COST Action has started — a four-year European network on neuromorphic computing. I am leading WG1: Foundations & Theoretical Models. Our question: when does a biological mechanism actually buy you something computationally, and when should it be deliberately viola…

Recent commentary

Massive congrats to my PhD student @jajmca.bsky.social, co-supervised by John Wade & @conjh.bsky.social, who handed in his PhD thesis yesterday inside 3 years, virtually unheard of in the UK! Amazing theoretical/computational work linking structure to function in recurrent neural networks.

Surely the purpose of Trump's AI Force is to enable a surveillance state. More generally I am not so much worried about AGI or AI taking over humans, but humans using AI as a weapon for cyber attacks or a tool for mass surveillance on other humans.

circa 2010 during my PhD in a comp neuro/machine learning institute, at a computer vision seminar I asked a naive question and speaker said, yeah there is a running joke in ML that what we really need is 'a big model that knows everything'. Cue a chuckle from the audience How blind we were

I know people mourn the loss of the ability to use the em-dash for fear of suspicion of AI-ing their writing. But for me the big one is the rule of three - losing that has made me sad, frustrated, and even downright perturbed.

I teach a MSc module on Statistical Modelling and Machine Learning 4 years running, and every year without fail, I have to look up, many times, the difference between Type I and Type II errors Why were they not just named after some extinct eugenicists like everything else in statistics
