Sparse Representation and Low-rank Approximation Workshop at NIPS 2011 Invited Talk: Robust Sparse Analysis Regularization by Gabriel Peyré, CNRS, CEREMADE, Université Paris-Dauphine Abstract: In this talk I will detail several key properties of L1-analysis regularization for the resolution of linear inverse problems. Most previous theoretical works consider sparse synthesis priors where the sp...

Sparse Representation and Low-rank Approximation Workshop at NIPS 2011 Invited Talk: Dictionary-Dependent Penalties for Sparse Estimation and Rank Minimization by David Wipf, University of California at San Diego Abstract: In the majority of recent work on sparse estimation algorithms, performance has been evaluated using ideal or quasi-ideal dictionaries (e.g., random Gaussian or Fourier) char...
