Abstract : We leverage recent results from machine learning to show theoretically and practically that it is possible to stably recover a signal made of few spikes in the gridless setting from few random weighted Fourier measurements.
Given a free choice of frequencies, a number of measurements lower than with the traditional low-pass filter uniform sampling of low frequencies guarantees stable recovery.
