Title: Efficient Federated Learning via Variational Dropout. Abstract: As an emerging field, federated learning has recently attracted considerable attention.
Compared to distributed learning in the datacenter setting, federated learning
has more strict constraints on computate efficiency of the learned model and communication
cost during the training process. In this work, we propose an efficient
federated learning framework based on variational dropout. Our approach is able
to jointly learn a sparse model while reducing the amount of gradients exchanged
during the iterative training process. We demonstrate the superior performance
of our approach on achieving significant model compression and communication
reduction ratios with no accuracy loss.
