Towards Mitigating Device Heterogeneity in Federated Learning via Adaptive Model Quantization
Ahmed M. Abdelmoniem, Marco Canini · 2021
Federated learning (FL) is increasingly becoming the norm for training models over distributed and private datasets. Major service providers rely on FL to improve services such as text auto-completion, virtual keyboards, and item recommendations. Nonetheless, training models with FL in practice requires significant amount of time (days or even weeks) because FL tasks execute in highly heterogeneous environments where devices only have widespread yet limited computing capabilities and network connectivity conditions.
