Have a restful holiday everyone* *or you can blast this at 100 decibels m.youtube.com/watch?v=LDPw...

Home finally

Puzzle: which flight mainly* goes East on the outbound journey and mainly goes East on the return journey? Clue: I did not see Santa *the pilot said this means going East for most of the journey

Somehow loud Frank Sinatra is not good for jet lag at 6am

I told the cheerful dog that I have to start the 4-day journey home

“I did not want to make this hike too easy”

Stochastic gradient ascent

This is going on all day when we are usually writing grants

I have borrowed a cheerful dog to walk in the Himalayas

Friday afternoon

Tea time

COME JOIN US for our sessions today on Multimodal Computer Vision - I’ll do a plenary tutorial on vision language models and other cross modal (genome-image) AI models, with new uniform convergence bounds (ie how much training data do you need) #ICVGIP

Afternoon meditation

Apparently the conference I am speaking at is this way (this is the 4th day of travel to get there :)

I have to do the ENIGMA End of Year Zoom call from 1130pm-1am in Chandigarh. Should I do it from my hotel room and annoy the people trying to sleep in the next room or try to haggle with the hotel to keep the business center open after midnight ?

Today I learned you can be fit 6 vehicles in 3 lanes of traffic* so long as everyone is paying attention

Sunday morning mad dash to airport, flash flood warning

Cortical expansion and genetic risk for PD. Led by Houman Azizi and Nooshin Abbasi. With @ptenigma.bsky.social @misicbata.bsky.social @yasharneuro.bsky.social @ndrewvo.bsky.social and many others www.medrxiv.org/content/10.6...

🔥OK I have honestly written a new computer vision lecture for next week's #ICVGIP2025 keynote 🔥 *a very jet-lagged 13.5 time-zones ahead, so strong coffee needed! *yes it's yellow as I have bad eyesight and could help if I can read my own slides ;)

440pm

Home * *somehow you fly over LA for about half an hour, even though it is not 300 miles wide

Flight delayed, but heading home (probably)

🔥 I’ll be at Emory in Atlanta for a couple of days* if anyone wants to have a cup of tea or say hello ! Will be spekaing @ Emory AI Health Conference, organised by the amazing Drs Anant Madabhushi, Saima Rathore, Satish E. Viswanath 📅 December 2–3, 2025 📍 Emory University 👉 Program in comment

Well played USC 14 UCLA 10 13:38 to go 4th qtr

USC v UCLA - May the best team win ;)

🧩 Today's experiment (PDEs on Sierpiński networks)

🤯Can you get Claude to output an animated GIF or MP4? It outputs results to a webpage [1], but I can't download it as a video. (It's for a talk) I tried gifcap.dev to screen-record but you can't see the smooth flow on the network edges *it's a Sierpiński flow (PDE on a Sierpiński lattice)

450pm

440pm

It kind of works and is strangely pleasing ! *But my daughter said "I am not sure how this helps me to arrange the lights" :)

🔥 OK just for fun, here's a holiday puzzle for you.... 🔥 "How to Light a Tree with Stein Variational Gradient Descent" aiandthebrain.substack.com/p/how-to-lig...

End of the rain

🔥You will see in general that brains, societies of humans, and AI are all networks, and the best synergies of all 3, or of 2 of them, involve networks with mutual feedback 🔥For example, AI is being improved by humans iteratively improving it, not just by backpropagation 👇

An intriguing interview [1] with my fellow Yorkshireman+inimitable brain mapper Dr Karl Friston on the free energy principle +social networks* *you will often see a modular hierarchical organisation emerging in human consortia to rapidly communicate information via dual graphs as we noted in [2]

4:49pm

🔥 Brilliant guided tour from the ORIGAMI Lab showing how they are bringing Nipoppy and Neurobagel infrastructure to ENIGMA-Parkinson’s to power large-scale multisite data integration 🔥 PAPER: apertureneuro.org/article/1450...

Looking forward to teaching our #USC neuroscience PhD students tomorrow, 32 years after starting as a nervous new student who knew 0 neuroscience :) Fortunately the main textbook now weighs 9 pounds - 3.5 times heavier than in 1993 !! @USCNGP

🔥 DOES SCHIZOPHRENIA have SUBTYPES? What about other brain disorders? 🔥 Brilliant new paper www.nature.com/articles/s41... by @alisaffet.bsky.social +Cemre Candemir of the SoCaT lab (pictured) explains how 'biotypes' are defined, + why 🔥 Explained more in this VIDEO: www.youtube.com/watch?v=nPH-...

Ha ha! Made me think of this gem … youtu.be/NX3_APn3icQ

The plane turned left in the end :)

🔥 Global AI-Brain Initiative (AI and the Brain) aiandthebrain.substack.com/p/global-ai-... (a post for our new students; some links in it may be more widely interesting!)

from now on I am going to begin all papers with "Any serious consideration..."

Pilot seems to have gone the wrong way* *I hope they turn left at the North Pole

Quick escape from airport during layover
