@SebastianSeung It was super interesting and confusing at the same time!

There he co-taught a legendary class on "Physics of Computation" with VLSI giant Carver Mead and physics giant Richard Feynman. Don't you wish you could jump in a time machine and take that class? caltech.edu/about/news/cal…

Wow. Hopfield model and Boltzmann machine.
The Nobel Prize@NobelPrize
BREAKING NEWS The Royal Swedish Academy of Sciences has decided to award the 2024 #NobelPrize in Physics to John J. Hopfield and Geoffrey E. Hinton “for foundational discoveries and inventions that enable machine learning with artificial neural networks.”

@msftksrini We have a methods paper just posted to arxiv: arxiv.org/pdf/2308.02707… .. but haven't published the results from the trial yet

We've shown (in a live trial) that we have a statistically significant method for avoiding contrails. blog.google/technology/ai/… #climatechange

Electricity use at data centers did NOT skyrocket.
In fact, despite massive growth in computation and data storage provided, total electricity use barely budged.

Nicely cleaning up an ugly thresholding hack in diffusion models.

Is Elden Ring an existential risk to humanity? That is the question I consider in my new blog post. Yes, it is a comment on the superintelligence/x-risk debate. Read the full thing here:

From a techno-economic grid study, fusion needs to reach relatively modest capital cost goals to take off.

I got really excited that the LLaMA paper calculates and reports their carbon footprint! 🦙🌬️🌎
But upon looking at the paper itself, it has this table, which completely misconstrues the emissions of OPT and BLOOM, while not actually reporting LLaMA's own.
How? A thread 🧵

We’re proud to share promising new research published in @SpringerNature’s @NatureComms journal. Along with our partners at @NIFSplasma in Japan, TAE has conducted the first-ever hydrogen-boron fusion experiments in a magnetically confined fusion plasma. rdcu.be/c52Ym

For DECADES we've assumed the surface code uses 4 couplers per qubit. But change perspective a bit, and it's clear it works just as well with 3 couplers per qubit. Same distance, same # of gate layers, same footprint.
Also 23 other circuit variations: arxiv.org/abs/2302.02192
Matt McEwen@mattjmcewen
Forget what you know about surface code circuits: arxiv.org/abs/2302.02192 Our new work harnesses the time-dynamics of circuits to do the surface code on a hex-grid, use ISWAP gates, and move the patch. These circuits relax hardware requirements without reducing performance. 1/9

People are asking if there are alternatives to RL in RLHF. Yes, imitation with DAGGER (tutorial: ri.cmu.edu/publications/a… ). The user provides feedback with corrections, e.g. when the agent says “that” the user tells the agent that instead of saying “that”, it should say “this”.
Jay Alammar@JayAlammar
This. People are perhaps too quick to attribute favorable results to the RL piece of this formula.

I've used Vizier: it's quite robust. Recommended.
Zoubin Ghahramani@ZoubinGhahrama1
I'm super excited we've open sourced Vizier! Vizier is Google's scaled blackbox optimization system. It has had a huge impact internally across many products and has helped tune millions of ML models at Google! We hope this is valuable to the broader community.
