Sample-Efficient Low Rank Phase Retrieval

Seyedehsara Nayer, Namrata Vaswani

This work studies the Low Rank Phase Retrieval (LRPR) problem: recover an $n \times q$ rank- $r$ matrix $X^{*}$ from $y_{k} = ∣ A_{k}^{⊤} x_{k}^{*} ∣$ , $k = 1, 2, ..., q$ , when each $y_{k}$ is an m…

Provable Low Rank Phase Retrieval

Seyedehsara Nayer, Praneeth Narayanamurthy, Namrata Vaswani

We study the Low Rank Phase Retrieval (LRPR) problem defined as follows: recover an $n \times q$ matrix $X^{*}$ of rank $r$ from a different and independent set of $m$ phaseless (mag…

Phaseless Subspace Tracking

Seyedehsara Nayer, Namrata Vaswani

This work takes the first steps towards solving the "phaseless subspace tracking" (PST) problem. PST involves recovering a time sequence of signals (or images) from phaseless linea…
