Our joint work with @YohannDCstr and Vincent Duval is finally out: arxiv.org/abs/2307.03709 "Exact recovery of the support of piecewise constant images via total variation regularization"

New preprint "A convex lifting approach for the Calderón problem", by @GSAlberti, @rom1petit and @SimoneSanna1893

@astanziola42 @malga_center Here it is: arxiv.org/abs/2402.00737 (sorry for the delay)!

@malga_center @rom1petit Is there a paper for the inverse scattering talk? :)

Our faculty @GSAlberti, @matsanta, Cesare Molinari, post-doc @rom1petit and #PhD student Alessandro Felisi took part in the AIP conference on 04-08 September in Göttingen, Germany. #inverseproblems #harmonicanalysis #partialdifferentialequations #machinelearning #optimization

@astanziola42 @malga_center Not yet, we're still working on the experiments! Will DM you as soon as we upload it!

Nice workshop in Paris in november (I'll be there) "Off-the-grid and continuous methods for optimization and inverse problems in imaging" indico.math.cnrs.fr/event/10418/

2 postdocs available at @malga_center: - inverse problems and machine learning, co-supervised by @matsanta (@UniGenova) - optimization for nonlinear inverse problems, co-supervised by Clarice Poon (@warwickmaths), funded by @ERC_Research project SAMPDE #open-positions" target="_blank" rel="nofollow noopener">malga.unige.it/#open-positions

I should have stressed that our analysis DOES NOT cover the denoising case. We rely on some regularity assumption on the measurement operator. It is for example satisfied by the convolution with any C^1 kernel, possibly followed by a subsampling.

All our experiments can be reproduced using the notebook available here: github.com/rpetit/2023-su…

@malga_center 👋

A warm welcome to our CHarML newcomers! Best of luck to #Postdoc Romain Petit, working on #inverseproblems in #imaging, and #PhDstudent Paolo Angella, working on #machinelearning methods for #MRI. 👏 #malga_center

@BrunoLevy01 Looks really cool!! Are the small holes appearing and disappearing quickly some kind of "topological noise" you add on purpose?
