University of Bath, 1 June 2017

Compressive sensing is a powerful mathematical theory widely used in Statistics, Computer Science, Engineering and Physics.

Central to this theory is that sparse quantities can be reconstructed using a small number of random measurements.

Recent years have seen an explosion of research activities within this interdisciplinary field, and compressive sensing techniques have now become of key importance in signal processing applications, including medical and astronomical imaging.

Bringing together world-renowned experts and early career researchers, this workshop will:

• give participants a common understanding of the theory of compressive sensing
• present recent theoretical and algorithmic developments within the field
• address key applications

The workshop will also cover interconnected areas including:

• sampling paradigms
• theoretical estimates and algorithms for recovery
• TV regularisation
• radio-interferometric astronomical imaging
• tomographic imaging
• Throughout the workshop, there will be ample networking opportunities aimed at fostering collaborations between scientists in the field of compressive sensing.
