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…
Exact Thresholds for Noisy Non-Adaptive Group Testing
Junren Chen, Jonathan Scarlett
In recent years, the mathematical limits and algorithmic bounds for probabilistic group testing have become increasingly well-understood, with exact asymptotic thresholds now being…
Concomitant Group Testing
Thach V. Bui, Jonathan Scarlett
In this paper, we introduce a variation of the group testing problem capturing the idea that a positive test requires a combination of multiple ``types'' of item. Specifically, we…
Approximate Message Passing with Rigorous Guarantees for Pooled Data and Quantitative Group Testing
Nelvin Tan, Pablo Pascual Cobo, Jonathan Scarlett +1
In the pooled data problem, the goal is to identify the categories associated with a large collection of items via a sequence of pooled tests. Each pooled test reveals the number o…
