10–13 September 2018 5th International Workshop on Compressed Sensing applied to Radar, Multimodal Sensing and Imaging

University of Siegen, Germany, Center for Sensorsystems (ZESS)

The idea of the CoSeRa workshops is to join world-class scientists, engineers and educators engaged in the fields of Compressive Sensing (CS) with a wide scope of applications to Radar, optical and nonoptical 2D/3D imaging, material analysis surface and subsurface inspection by ultrasonic, microwave, TeraHertz as well as X-ray techniques. CoSeRa covers the complete sensoric chain from novel type of sensors, hardware concepts over sensor signal processing to high level information extraction/mining concepts adopting the paradigms of CS at every stage.
Originally intended as a new sensing paradigm to overcome the limitations of Shannon/Nyquist’s sampling theorem under certain (and well defined conditions), compressed sensing has meanwhile turned into a novel way of thinking or looking at the complete world of sensorics and sensor information extraction. The idea of “sparse or parsimonious modelling (putting Occam’s razor into the centre of interpreting physical phenomena) in itself is much older than the compressed sensing theory, but it is without doubt the merit of mathematical CS, to have introduced the background to give sufficient conditions under which sparse modelling concepts can turn nominally underdetermined systems of equations into well behaved, even over determined systems of equations and furthermore to prove optimality for such cases. In parallel the power of using sparsity as (not necessarily the only) one important regularization constraint in inversion algorithms developed, opening up the door to the world of optimization theory.
In a certain way the concepts and paradigms of Compressive Sensing may be considered as the answer to the curse of exploding data dimensions, which is modernistically and popularistically coined, but not solved by the term “big data”. Compressive Sensing substitutes the term “big” by “smart”.
Yet as the name indicates it will be always the sensoric problems arising from the applications which determine the background and allow to formulate the application dependent constraints, still obeying Occams’s razor, however. It is exactly this engineering embedding which turns abstract mathematical models with the least possible number of prior assumptions into valid engineering models with the maximum possible number of additional but “non informative priors” in order to extract the highest possible information amount out of noisy data.
Upon this background, we believe that the combination of invited key-speeches and contributed talks will allow the formation of a most interesting technical program and setup the stage for an extremely productive interaction and exchange between mathematicians, engineers and application domain people.
As any interaction and cooperation of experts can only grow within the scope of a holistic workshop concept respecting all levels of communication, we are additionally taking highest efforts to not only setup up a scientifically and technically outstanding programme, but also to make its participants feel be taken extremely good care of, with a thrilling social and also accompanying persons programme. Siegen and its surroundings offer an abundance of opportunities, beautiful landscape (Siegen is the greenest city of Northrhine Westfalia), forests lakes, wildlife Wisent resorts and last but not least, one world known brewery (“Krombacher”) where a visiting excursion will be part of the social programme.
With intensive and careful planning underway we anticipate a technically outstanding and most pleasant workshop.

We look forward to seeing you in Siegen in September 2018.
