Dynamic Network-Assisted D2D-Aided Coded Distributed Learning
share
Today, various machine learning (ML) applications offer continuous data processing and real-time data analytics at the edge of a wireless network. Distributed ML solutions are seriously challenged by resource heterogeneity, in particular, the so-called straggler effect. To address this issue, we design a novel device-to-device (D2D)-aided coded federated learning method (D2D-CFL) for load balancing across devices while characterizing privacy leakage. The proposed solution captures system dynamics, including data (time-dependent learning model, varied intensity of data arrivals), device (diverse computational resources and volume of training data), and deployment (varied locations and D2D graph connectivity). We derive an optimal compression rate for achieving minimum processing time and establish its connection with the convergence time. The resulting optimization problem provides suboptimal compression parameters, which improve the total training time. Our proposed method is beneficial for real-time collaborative applications, where the users continuously generate training data.
