Byzantine-Resilient Federated Alternating Gradient Descent and Minimization for Partly-Decoupled Low Rank Matrix Learning

Ankit Pratap Singh, Ahmed Ali Abbasi, Namrata Vaswani

ICML 2025poster

This work has two contributions. First, we introduce a provably secure (Byzantine-resilient) sample- and communication-efficient alternating gradient descent (GD) and minimization based algorithms for solving the federated low rank matrix completion (LRMC) problem. This involves learning a low rank…

r-Local Unlabeled Sensing: Improved Algorithm and Applications

Ahmed Ali Abbasi, Abiy Tasissa, Shuchin Aeron

ICASSP 2022accepted

The unlabeled sensing problem is to solve a noisy linear system of equations under unknown permutation of the measurements. We study a particular case of the problem where the permutations are restricted to be r-local, i.e. the permutation matrix is block diagonal with r×r blocks. Assuming a Gaussia…
