WORKSHOP PROCEEDINGS

The aim of the iTWIST workshop is to foster collaboration between international scientific teams for developing new theories, applications and generalizations of the “sparsity paradigm”. This is why this event emphasizes dissemination of ideas through both specific oral/poster presentations and free discussions.

The registration fees (200€ before 1st of July / 250€ from 1st of July) includes all lunches, coffee breaks and the social event (more information on the iTWIST’16 website).

For this edition, iTWIST’16 will feature invited talks, oral presentations and posters. The workshop welcomes 2-page extended abstracts on any aspects of the following themes:

Themes

  • Sparsity-driven data sensing and processing (e.g., optics, computer vision, genomics, biomedical, digital communication, channel estimation, astronomy)
  • Application of sparse models in non-convex/non-linear inverse problems (e.g., phase retrieval, blind deconvolution, self calibration)
  • Approximate probabilistic inference for sparse problems
  • Sparse machine learning and inference
  • "Blind" inverse problems and dictionary learning
  • Optimization for sparse modelling
  • Information theory, geometry and randomness
  • Sparsity? What's next?
    • Discrete-valued signals
    • Union of low-dimensional spaces,
    • Cosparsity, mixed/group norm, model-based, low-complexity models, ...
  • Matrix/manifold sensing/processing (graph, low-rank approximation, ...)
  • Complexity/accuracy tradeoffs in numerical methods/optimization
  • Electronic/optical compressive sensors (hardware)

PUBLICATION OF PROCEEDINGS

Submissions will be published in open access proceedings on arXiv without any copyright restrictions to
facilitate publication of further details elsewhere. Recycling recent published/submitted works is also au-
thorized as a means to sustain interesting discussions during the workshop.

The workshop proceedings are currently being finalised.
