Self-Duplicating Random Walks for Resilient Decentralized Learning on Graphs

no code implementations16 Jul 2024 Maximilian Egger, Ghadir Ayache, Rawad Bitar, Antonia Wachter-Zeh, Salim El Rouayheb

We propose a decentralized algorithm called DECAFORK that can maintain the number of RWs in the graph around a desired value even in the presence of arbitrary RW failures.

Walk for Learning: A Random Walk Approach for Federated Learning from Heterogeneous Data

no code implementations1 Jun 2022 Ghadir Ayache, Venkat Dassari, Salim El Rouayheb

One of the main challenges of FL is the communication bottleneck between the nodes and the parameter server.

Federated Learning

Private Weighted Random Walk Stochastic Gradient Descent

no code implementations3 Sep 2020 Ghadir Ayache, Salim El Rouayheb

To speed up the convergence, we propose instead to study random walk based SGD in which a global model is updated based on a random walk on the graph.
