---+++ Please join us for SPARS 2015 in beautiful and exciting Cambridge, UK.

The Signal Processing with Adaptive Sparse Structured Representations SPARS workshop seeks novel ideas and results, both experimental and theoretical, for adaptive sparse representations, sampling and computational methods for high-dimensional data that feature structured combinatorial and geometric foundations.

SPARS 2015 will take place at Robinson College, Cambridge, from July 6th to July 9th, 2015 and we welcome you! The conference banquet will take place in the 400-year-old Great Hall of Trinity College.
