On Learnability, Complexity and Stability
Silvia Villa, Lorenzo Rosasco, Tomaso Poggio
We consider the fundamental question of learnability of a hypotheses class in the supervised learning setting and in the general learning setting introduced by Vladimir Vapnik. We…
Proximal methods for the latent group lasso penalty
Silvia Villa, Lorenzo Rosasco, Sofia Mosci +1
We consider a regularized least squares problem, with regularization by structured sparsity-inducing norms, which extend the usual and the group lasso penalty, by allowing…
Nonparametric sparsity and regularization
Lorenzo Rosasco, Silvia Villa, Sofia Mosci +2
In this work we are interested in the problems of supervised learning and variable selection when the input-output dependence is described by a nonlinear function depending on a fe…
PADDLE: Proximal Algorithm for Dual Dictionaries LEarning
Curzio Basso, Matteo Santoro, Alessandro Verri +1
Recently, considerable research efforts have been devoted to the design of methods to learn from data overcomplete dictionaries for sparse coding. However, learned dictionaries req…
