Shrinkage Rules for Variational Minimization Problems and Applications to Analytical Ultracentrifugation
Martin Ehler
Finding a sparse representation of a possibly noisy signal can be modeled as a variational minimization with l_q-sparsity constraints for q less than one. Especially for real-time,…
