Privacy Preserving Semi-Decentralized Mean Estimation over Intermittently-Connected Networks

Rajarshi Saha, Mohamed Seif, Michal Yemini +2

We consider the problem of privately estimating the mean of vectors distributed across different nodes of an unreliable wireless network, where communications between nodes can fai…

Compressing Large Language Models using Low Rank and Low Precision Decomposition

Rajarshi Saha, Naomi Sagan, Varun Srivastava +2

The prohibitive sizes of Large Language Models (LLMs) today make it difficult to deploy them on memory-constrained edge devices. This work introduces -- a new post-tr…

Semi-Decentralized Federated Learning with Collaborative Relaying

Michal Yemini, Rajarshi Saha, Emre Ozfatura +2

We present a semi-decentralized federated learning algorithm wherein clients collaborate by relaying their neighbors' local updates to a central parameter server (PS). At every com…

Robust Federated Learning with Connectivity Failures: A Semi-Decentralized Framework with Collaborative Relaying

Michal Yemini, Rajarshi Saha, Emre Ozfatura +2

Intermittent connectivity of clients to the parameter server (PS) is a major bottleneck in federated edge learning frameworks. The lack of constant connectivity induces a large gen…

Minimax Optimal Quantization of Linear Models: Information-Theoretic Limits and Efficient Algorithms

Rajarshi Saha, Mert Pilanci, Andrea J. Goldsmith

High-dimensional models often have a large memory footprint and must be quantized after training before being deployed on resource-constrained edge devices for inference tasks. In…

Partner-Aware Algorithms in Decentralized Cooperative Bandit Teams

Erdem Bıyık, Anusha Lalitha, Rajarshi Saha +2

When humans collaborate with each other, they often make decisions by observing others and considering the consequences that their actions may have on the entire team, instead of g…

Efficient Randomized Subspace Embeddings for Distributed Optimization under a Communication Budget

Rajarshi Saha, Mert Pilanci, Andrea J. Goldsmith

We study first-order optimization algorithms under the constraint that the descent direction is quantized using a pre-specified budget of -bits per dimension, where $R \in (0 ,\…

Decentralized optimization over noisy, rate-constrained networks: Achieving consensus by communicating differences

Rajarshi Saha, Stefano Rini, Milind Rao +1

In decentralized optimization, multiple nodes in a network collaborate to minimize the sum of their local loss functions. The information exchange between nodes required for this t…
