Adaptive Denoising of Signals with Local Shift-Invariant Structure
Zaid Harchaoui, Anatoli Juditsky, Arkadi Nemirovski +1
We discuss the problem of adaptive discrete-time signal denoising in the situation where the signal to be recovered admits a "linear oracle" -- an unknown linear estimate that take…

Efficient First-Order Algorithms for Adaptive Signal Denoising
Dmitrii Ostrovskii, Zaid Harchaoui
We consider the problem of discrete-time signal denoising, focusing on a specific family of non-linear convolution-type estimators. Each such estimator is associated with a time-in…
