Slope meets Lasso: improved oracle bounds and optimality

Pierre C. Bellec, Guillaume Lecué, Alexandre B. Tsybakov

We show that two polynomial time methods, a Lasso estimator with adaptively chosen tuning parameter and a Slope estimator, adaptively achieve the exact minimax prediction and $\ell…

Regularization and the small-ball method I: sparse recovery

Guillaume Lecué, Shahar Mendelson

We obtain bounds on estimation error rates for regularization procedures of the form \begin{equation*} \hat f \in {\rm argmin}_{f\in F}\left(\frac{1}{N}\sum_{i=1}^N\left(Y_i-f(X_i)…
