- Sep 4, 2025 Sparse Sampling and the Limits of Recovery Why a sub-Nyquist sample count can still determine a sparse signal, what the restricted isometry property guarantees, and where the guarantee stops being useful. scientific computing
- May 14, 2025 Linear Sketches and Recovering Sparse Signals from Bucket Measurements How a sketch that only stores bucket sums can still return the identities of heavy items, why recovery needs a median over rows, and what the restricted isometry property guarantees. algorithms
