F. Krahmer, C. Kümmerle and H. Rauhut. A Quotient Property for Matrices with Heavy-Tailed Entries and its Application to Noise-Blind Compressed Sensing, 2018. |
Abstract At the same time, our results establish robustness of noise-blind l1-decoders for recovering sparse vectors x from underdetermined, noisy linear measurements y=Ax+w under the weakest possible assumptions on the entrywise distributions that allow for recovery with optimal sample complexity even in the noiseless case. Our analysis predicts superior robustness behavior for measurement matrices with super-Gaussian entries, which we confirm by numerical experiments. |
