Sample-Optimal Fourier Sampling in Any Constant Dimension
We give an algorithm for ℓ[subscript 2]/ℓ[subscript 2] sparse recovery from Fourier measurements using O(k log N) samples, matching the lower bound of Do Ba-Indyk-Price-Woodruff'10 for non-adaptive algorithms up to constant factors for any k ≤ N [superscript 1-δ]. The algorithm runs in Õ(N) ti...
