Robust Instance Optimal Phase-Only Compressed Sensing

Junren Chen, Michael K. Ng, Jonathan Scarlett

Phase-only compressed sensing (PO-CS) concerns the recovery of sparse signals from the phases of complex measurements. Recent results show that sparse signals in the standard spher…

Uniform Recovery Guarantees for Quantized Corrupted Sensing Using Structured or Generative Priors

Junren Chen, Zhaoqiang Liu, Meng Ding +1

This paper studies quantized corrupted sensing where the measurements are contaminated by unknown corruption and then quantized by a dithered uniform quantizer. We establish unifor…

Solving Quadratic Systems with Full-Rank Matrices Using Sparse or Generative Priors

Junren Chen, Michael K. Ng, Zhaoqiang Liu

The problem of recovering a signal $x \in R^{n}$ from a quadratic system ${y_{i} = x^{⊤} A_{i} x, i = 1, \dots, m}$ with full-rank ma…
