About:

Inverse problems and imaging applications are everywhere, and often there is a need for assessing the uncertainty of the reconstructions due to noise, model errors, etc. by means of uncertainty quantification (UQ). Development of UQ methods requires collaboration across several areas.

This workshop will bring together specialists in UQ for inverse problems and imaging, and we invite talks related to the development of theory, methodology, and software.  We also invite talks about interesting applications of UQ in imaging. The goal is to stimulate networking and collaboration between researchers and students in these areas, and to present state-of-the-art research results.

The workshop is supported by the project CUQI (Computational Uncertainty Quantification for Inverse problems) funded by the Villum Foundation (grant no. 25893) and by UKRI EPSRC BLOOM (EP/V006134/1) and LEXCI (EP/W007673/1).

​CUQIpy Software Tranining Course

CUQIpy is a python software package for computational uncertainty quantification for inverse problems, developed in the CUQI research project.

Before the main workshop, we give a training course on this software. Participants will learn to use CUQIpy to model statistical inverse problems and perform UQ on them. The course includes hands-on tutorials (bring your laptop!) with examples from image deblurring, X-ray CT, and inverse problems based on partial differential equations. Half of the course is devoted to working on a small use-case with CUQIpy, and participants are encouraged to bring their own case and data.

​Participation

Participation in person only.

​Programme

Monday morning is devoted to a brief tutorial on Bayesian inference and UQ for inverse problems.

The CUQIpy training course lasts from Monday noon until Tuesday noon; Monday evening is available for the nerds.

The core workshop lasts from Tuesday noon until Friday noon, and consists of plenary talks, contributed talks, and poster sessions. There will be a welcome reception on Tuesday evening, and on Thursday evening there will be a guided tour followed by the workshop dinner.

For those who stay on Friday afternoon, we arrange a social event – perhaps a visit to a whisky or gin distillery.
