Deep learning and inverse problems

Information:

we have been made aware of a very convincing phone scam that is focusing on our workshop participants. Participants may be contacted by phone by a firm called Business Travel Management to arrange accommodation for workshops and/or programmes.  This includes a request to enter credit card information.

Please note, INI will never contact you over the phone requesting card details. We take all payments via the University of Cambridge Online store https://onlinesales.admin.cam.ac.uk/.

If you have been contacted by this company please contact us as soon as possible.

Workshop
27th September 2021 to 1st October 2021
Organisers: 
Simon Arridge

Workshop theme:

Classical research on inverse problems has focused on establishing conditions which guarantee that solutions to ill-posed problems exist and on methods for approximating solutions in a stable way in the presence of noise. Despite being very successful, such a knowledge-driven approach is also associated with some shortcomings. First of all, a mathematical model is never complete. Secondly, most applications will have inputs which do not cover the full space but stem from an unknown subset or obey an unknown stochastic distribution.

For these reasons, recent research in inverse problems seeks to develop a mathematically coherent foundation for combining classical model-driven approaches, with data-driven models, and in particular those based on deep learning. As an application area of deep learning, inverse problems, however, occupy a special role as the inherent and unavoidable instability of inverse problems - which cannot be remedied by preconditioning or any other type of data preprocessing - is reflected by the failure of naively transferring deep learning concepts from image processing directly to inverse problems in tomography, non-destructive testing or monitoring physical-technical processes in general.

So far several concepts with stunning experimental results have been published for combining model-based approaches for inverse problems with DNNs, however, no consistent theory exists. We expect that discussions at and collaborations stemming from this workshop will contribute towards the creation of a mathematically sound theory and they have the potential to shape future mathematical research in this field.
