Abstract
This article investigates the support detection problem using the LASSO estimator in the space of measures. More precisely, we study the recovery of a discrete measure (spike train) from few noisy observations (Fourier samples, moments, etc.) using an â1-regularization procedure. In particular, we provide an explicit quantitative localization of the spikes.
