Optimal Frames for Phase Retrieval Linked to Polygon Geometry

Optimal frames for phase retrieval map to polygons that maximize perimeter for a fixed diameter, and harmonic frames aren’t optimal for any even m ≥ 4. Read more: getnews.me/optimal-frames-for-phase... #phaseretrieval #polygongeometry #harmonicframes

Event-Based Vision Sensors Enable Faster, Low‑Light Phase Retrieval

Researchers used an event‑based vision sensor with sub‑millisecond latency, showing event capture removed sequential exposures and improved low‑light phase retrieval. Read more: getnews.me/event-based-vision-senso... #eventbasedvision #phaseretrieval

Stable Phase Retrieval: Optimal Rates in Poisson & Heavy‑Tailed Noise

Researchers show that in the Poisson regime, non-convex and convex least-squares estimators attain the minimax-optimal O(√n/m) error bound; the preprint was posted on 1 Oct 2025. getnews.me/stable-phase-retrieval-o... #phaseretrieval #poissonnoise

New Study Evaluates Amplitude-Based Models for Low-Rank Matrix Recovery

Researchers show amplitude‑based methods can recover low‑rank matrices from noisy magnitude data, proving error ≈ ‖η‖₂/√p when measurements p ≳ (m+n)r. Sep 2025. Read more: getnews.me/new-study-evaluates-ampl... #phaseretrieval #lowrank

New Algorithm Boosts Sample Efficiency in Sparse Phase Retrieval

gESP initialization expands the class of signals recoverable with Ω(k log n) sample complexity in sparse phase retrieval and needs fewer measurements than prior methods. Read more: getnews.me/new-algorithm-boosts-sam... #sparse #phaseretrieval
