iTWIST 2020: replays now available online

iTWIST 2020 (International Traveling Workshop on Interactions between low-complexity data models and Sensing Techniques) was held online from Centrale Nantes. Replays of all the lectures and conferences are now available online.

on December 10, 2020

The iTWIST workshop aims at fostering collaboration between international scientific teams for developing new theories, applications and generalizations of low-complexity models.

For this edition, iTWIST was divided into two parts, a 2-day doctoral school (30 November - 1 December) followed by the workshop over three days (2 - 4 December)

The replays are available to view online here:

The advent of increased computing capabilities, along with recent theoretical and numerical breakthroughs in the fields of signal processing, computational harmonic analysis, inverse problem solving, high-dimensional statistics and convex optimization, have boosted interactions between low-complexity data models (e.g., sparse or low-rank data models) and novel data sensing techniques.

In a nutshell, low-complexity data models aim at capturing, modeling and exploiting “just the information you need” in the ubiquitous data deluge characterizing any scientific or technological achievements. High dimensional objects can be thus reconstructed using little information. However, further developments and novel ideas are still required to meet new challenges, especially for efficiently dealing with complex data structures of “real life” applications and for interconnecting such models with other theoretical and applied fields.
