SPARS 2017

The Signal Processing with Adaptive Sparse Structured Representations (SPARS) workshop will bring together people from statistics, engineering, mathematics, and computer science, working on the general area of sparsity-related techniques and computational methods, for high dimensional data analysis, signal processing, and related applications.

SPARS 2017 will be held at Instituto Superior Técnico, the engineering school of the University of Lisbon, on June 5-8, 2017, and will be co-hosted by Instituto de Telecomunicações. The workshop venue will be the IST Congress Center.

In addition to 8 plenary lectures by world renowned experts, the workshop will feature a single track format with 34 talks and 4 poster sessions. Lunch will be provided on-site. The social program will include a welcome reception and a banquet.

SPARS 2017 is supported by the EU Marie Skłodowska-Curie Innovative Training Networks MacSeNet and SpaRTaN. In order to open the event to as many people as possible, attendance for the first day, June 5, is free. If you are not registered for SPARS, but would like to attend the first day, please email with your name and affiliation.
