On the SIAM News Blog, Ayush Bhandari explains that the unlimited sensing framework improves upon traditional #digitization by treating #quantization noise errors as data and saving bits by folding signals instead of clipping them. Read more here!

Feels like a passing of the torch between fields. When I was a teenager in the 1980s, after a half-century of monumental progress powered by theoretical physics, most smart high schoolers wanted to do physics. Upon arriving as an undergrad at MIT in 1988, it quickly became clear that the next big thing was computer science.
Congratulations to @geoffreyhinton and John on this honor. Interestingly, I met John Hopfield a long time before I met Geoff. ( In mid 1990s when he invited me to give a guest lecture in his Princeton ugrad class about my algorithm for traveling salesman. )
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 βfor foundational discoveries and inventions that enable machine learning with artificial neural networks.β

Had a great time photographing the #EclipseSolar2024 in Hemmingford, QC today! Totality is surrealβthe sun turns into a black hole and the horizon all around turns crimson. We caught a solar prominence too! (a massive loop of the sun's plasmaβinset below).

I've proven the strangest result of my career..
The classic idea that gradient descent's rate is bestΒ with constant stepsizesΒ 1/L is wrong. The idea that we need stepsizes in (0,2/L) for convergence is wrong.
Periodic long steps are better, provably.

International Conference on Computational Photography (iccp-conference.org/) just got underway in person in Haifa! The first in-person, post-covid mtg that I am aware of.
Have a look and see what the near future (in imaging and life) will look like!

For a PhD student, choosing a good lab is 10 times more important than choosing a particular topic to study

This is awesome. At @LightOnIO we do something entirely different to deal with high dynamic range but this work by Ayush seems to *rock*.

I have another funded vacancy for a PhD student to work on the topic of #robotic In-Hand-Manipulation & variable-friction grippers at Imperial.
The position is for home students only, which includes EU applicants if they can start before August 2021.
