Numerically Stable Binary Coded Computations.
2021 · arXiv (Cornell University)
This paper addresses the gradient coding and coded matrix multiplication problems in distributed optimization and coded computing. We present a numerically stable binary coding method which overcomes the drawbacks of the gradient coding method proposed …

Orthonormal Sketches for Secure Coded Regression
2022 · arXiv (Cornell University)
In this work, we propose a method for speeding up linear regression distributively, while ensuring security. We leverage randomized sketching techniques, and improve straggler resilience in asynchronous systems. Specifically, we apply a random orthonormal matrix …

Distributed Multi-User Secret Sharing
2018 · arXiv (Cornell University)
We consider a distributed secret sharing system that consists of a dealer, $n$ storage nodes, and $m$ users. Each user is given access to a certain subset of storage nodes, where it can download the …

Differentially Private Coded Computing
2023
Distributed computing has attracted significant recent attention for speeding up large-scale computations by disseminating computational jobs from a central master node across several worker nodes/servers. However, worker nodes are often untrusted and can also collude …
