Data Assimilation and Reduced Modeling for High Dimensional Problems

CIRM, Luminy, France
July 19-August 27, 2021


The goal of this event is to bring together scientists from both the academic and industrial communities to work and discuss on focused topics. The program includes:
  • 1-week summer school (July 19-23)
  • 5-week research session on projects proposed by academic scientists and/or industrial partners (July 26-August 27)
Participants may register to the summer school only or to the entire program. Junior participants may apply for fellowships to cover part or the whole stay. [More information coming soon].

Main topic

A significant challenge arising in increasingly many modern applications is how to blend complex mathematical models, often based on differential or integral equations, with the large and, possibly, noisy data sets which are now routinely available in many fields of engineering, science and technology. Growing efforts are made to develop a coherent mathematical framework where one of the main obstructions is the high dimensionality of the involved mathematical objects, which requires efficient sampling or optimization techniques for large-scale problems and, possibly, model order reduction strategies. The CEMRACS 2021 will be devoted to this topic of data assimilation and model reduction in high-dimensional problems. It is by nature interdisciplinary, not only by the amount of the different mathematical skills that need to be invoked, but also by the detailed knowledge that each specific application requires.

News on the event format in the context of the pandemic (last update on Jan. 15, 2021)

We will adapt the format depending on the epidemiological situation that we will have in the summer of 2021. The current most probable format is:
  • Summer school: Hybrid
  • Research Session: Fully on-site
Check here the sanitary measures that we will have.
