Asynchronous Diffusion Learning with Agent Subsampling and Local Updates

no code implementations8 Feb 2024 Elsa Rizk, Kun Yuan, Ali H. Sayed

In this work, we examine a network of agents operating asynchronously, aiming to discover an ideal global model that suits individual local datasets.

Decentralized Adversarial Training over Graphs

no code implementations23 Mar 2023 Ying Cao, Elsa Rizk, Stefan Vlaski, Ali H. Sayed

The vulnerability of machine learning models to adversarial attacks has been attracting considerable attention in recent years.

Enforcing Privacy in Distributed Learning with Performance Guarantees

no code implementations16 Jan 2023 Elsa Rizk, Stefan Vlaski, Ali H. Sayed

We study the privatization of distributed learning and optimization strategies.

Local Graph-homomorphic Processing for Privatized Distributed Systems

no code implementations26 Oct 2022 Elsa Rizk, Stefan Vlaski, Ali H. Sayed

We study the generation of dependent random numbers in a distributed fashion in order to enable privatized distributed learning by networked agents.

Privatized Graph Federated Learning

no code implementations14 Mar 2022 Elsa Rizk, Stefan Vlaski, Ali H. Sayed

Federated learning is a semi-distributed algorithm, where a server communicates with multiple dispersed clients to learn a global model.

A Graph Federated Architecture with Privacy Preserving Learning

no code implementations26 Apr 2021 Elsa Rizk, Ali H. Sayed

Thus in this work, we develop a private multi-server federated learning scheme, which we call graph federated learning.

Federated Learning under Importance Sampling

no code implementations14 Dec 2020 Elsa Rizk, Stefan Vlaski, Ali H. Sayed

Federated learning encapsulates distributed learning strategies that are managed by a central unit.

Federated Learning

Second-Order Guarantees in Federated Learning

no code implementations2 Dec 2020 Stefan Vlaski, Elsa Rizk, Ali H. Sayed

Federated learning is a useful framework for centralized learning from distributed data under practical considerations of heterogeneity, asynchrony, and privacy.

Optimal Importance Sampling for Federated Learning

no code implementations26 Oct 2020 Elsa Rizk, Stefan Vlaski, Ali H. Sayed

Federated learning involves a mixture of centralized and decentralized processing tasks, where a server regularly selects a sample of the agents and these in turn sample their local data to compute stochastic gradients for their learning updates.

Tracking Performance of Online Stochastic Learners

no code implementations4 Apr 2020 Stefan Vlaski, Elsa Rizk, Ali H. Sayed

The utilization of online stochastic algorithms is popular in large-scale learning settings due to their ability to compute updates on the fly, without the need to store and process data in large batches.

Dynamic Federated Learning

no code implementations20 Feb 2020 Elsa Rizk, Stefan Vlaski, Ali H. Sayed

Federated learning has emerged as an umbrella term for centralized coordination strategies in multi-agent environments.

Federated Learning

Network Classifiers With Output Smoothing

no code implementations30 Oct 2019 Elsa Rizk, Roula Nassif, Ali H. Sayed

This work introduces two strategies for training network classifiers with heterogeneous agents.
