Learning sparse structures for physics-inspired compressed sensing
Clément Dorffer, Thomas Paviet-Salomon, Gilles Le Chenadec +1
In underwater acoustics, shallow water environments act as modal dispersive waveguides when considering low-frequency sources. In this context, propagating signals can be described…

Efficient atom selection strategy for iterative sparse approximations
Clément Dorffer, Angélique Drémeau, Cedric Herzet
We propose a low-computational strategy for the efficient implementation of the "atom selection step" in sparse representation algorithms. The proposed procedure is based on simple…
