Fast and Sample-Efficient Federated Low Rank Matrix Recovery from column-wise Linear and Quadratic Projections

no code implementations20 Feb 2021 Seyedehsara Nayer, Namrata Vaswani

Finally, it can also be efficiently federated with a communication cost of only $nr$ per node, instead of $nq$ for projected GD.

Provable Low Rank Phase Retrieval

1 code implementation13 Feb 2019 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 (magnitude-only) linear projections of each of its columns.
