Gwen SAMAIN : PhD defense – Branch-and-bound algorithm for efficient resolution of sparse optimization problems.
Centrale Nantes, Amphi EAbstract: Numerous inverse problems in signal processing, statistics, biomedical imaging, astronomy and machine learning can be cast as the search for the best pattern combination fitting measurements, these patterns being taken from a known dictionary. The sparsity of the problem comes from the small number of patterns desired, using a l0 term. Several standard methods, […]
