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!

Great to have Giovanni at @imperialeee today, who gave an amazing talk on inverse problems. And hopefully first of more visits to come... !
Great to be at @imperialcollege today, despite it beat @UniofOxford for the first time in the @worlduniranking
Thanks @AB2World for the hospitality!
New Tutorial on ๐จ๐ป๐น๐ถ๐บ๐ถ๐๐ฒ๐ฑ ๐ฆ๐ฒ๐ป๐๐ถ๐ป๐ด at the upcoming @ieeeICASSP w/ @Ruiming999.
We'll cover the pet peeves of @IEEEsps: โข Sparse + sub-Nyquist Recovery โข Array Sig. Proc. โข Computatnal Imging โข Communication Sys. etc. from the lens of Modulo Non-linearities.

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 โfor foundational discoveries and inventions that enable machine learning with artificial neural networks.โ
๐ฃ๐ฟ๐ผ๐ป๐'๐ ๐ ๐ฒ๐๐ต๐ผ๐ฑ is a widely used, 200 years old technique. It estimates unknown parameters of K sine-waves from 2K samples.
In our new work (IEEE TSP, @IEEEsps) on Unlimited Sensing, we show that same can done with 6K+4 non-linear, modulo samples.

Thank you @ERC_Research.
Our idea is simple: Use ๐ค๐๐ฎ๐ป๐๐ถ๐๐ฎ๐๐ถ๐ผ๐ป ๐ก๐ผ๐ถ๐๐ฒ as the signal.
The gratifying part is that UG/MS students (@ImpEngineering) can get this and have already contributed to publications.
Here's an overview of our scientific vision.
Congrats to Dr Ayush Bhandari for securing a โฌ1.5M @ERC_Research grant.
His research in computational sensing aims to revolutionise digital information capture and will unlock new possibilities for applications across healthcare and communications.

After some encouragement frm frnds, we've put together a Tutorial on ๐๐ผ๐บ๐ฝ๐๐๐ฎ๐๐ถ๐ผ๐ป๐ฎ๐น ๐ฆ๐ฒ๐ป๐๐ถ๐ป๐ด for @eusipco2024.
This explores innovative methods of digitizing information at the intersection of Theory, Algorithms, Hardware, and Experiments.

Here for the summer school with friends including @AntheaMonod!
Quite a few but not possble to share here.
What tops the list is:
โ meeting Masha Gessen (~2018) who shared a few anecdotes about Grigori Perelman.
โ I was on a memorable boat trip with a Fields Medalist who also recntly recvd the Abel Prize. Got to learn about Yakov Sinai.
Had a great stay at @iiscbangalore, catching up with friends and researchers at @ecedeptiisc, some of whom I've known since 2010!
Glimpses from the 'Demos' on Unlimited Sensing at @ieeeICASSP, Seoul.
Although it requires a huge amount of wrk, my grp members and I have grwn to enjy demos as they truly bring our paprs to life, giving a clear sense of purpse.
Also more engaging and interactive.
Laurent is amazing! (@Laurent_Daudet)
I am still so happy that he was on my thesis committee. His unique depth and breadth of knowledge and thinking brought a lot of perspective to my work.

Another application of the Unlimited Sensing method. You can see the interplay of hardware and algorithms in action.
Over the last year, we have built a new ๐๐จ๐ฆ๐ฉ๐ฎ๐ญ๐๐ญ๐ข๐จ๐ง๐๐ฅ ๐๐๐๐๐ซ technology that leverages ๐๐จ๐๐ฎ๐ฅ๐จ ๐๐๐s, leading to new capabilities & advantages. See our live technology in action at @ieeeICASSP show-and-tell demo session A on Thursday.
