Fully Distributed Federated Learning with Efficient Local Cooperations
Evangelos Georgatos, Christos Mavrokefalidis, Kostas Berberidis · 2023
Recently, a shift has been observed towards the so-called edge machine learning, which allow multiple devices with local computational and storage resources to collaborate with the assistance of a centralized server. The well-known federated learning approach is able to utilize such architectures by allowing the exchange of only parameters with the server, while keeping the datasets private to each contributing device. In this work, we propose a communication-efficient, fully distributed, diffusion-based learning algorithm that does not require a parameter server and propose an adaptive combination rule for the cooperation of the devices. By adopting a classification task on the MNIST dataset, the efficacy of the proposed algorithm is demonstrated in non-IID dataset scenarios.
