SLS (Single Selection): a new greedy algorithm with an -norm selection rule
Ramzi Ben Mhenni, Sébastien Bourguignon, Jérôme Idier
In this paper, we propose a new greedy algorithm for sparse approximation, called SLS for Single L_1 Selection. SLS essentially consists of a greedy forward strategy, where the sel…

Some detection tests for low complexity data models and unknown background distribution
D. Mary, S. Bourguignon, E. Roquain +2
We consider several detection situations where, under the alternative hypothesis, the signal admits a low complexity model and, under both the null and the alternative hypotheses,…

Efficiency of BRDF sampling and bias on the average photometric behavior
Frederic Schmidt, Sebastien Bourguignon
The Hapke model has been widely used to describe the photometrical behavior of planetary surface through the Bi-directional Reflectance Distribution Function (BRDF), but the uncert…
