Bases:
Aggregator
SCAFFOLD Aggregator.
Paper: https://arxiv.org/pdf/1910.06378 The aggregator acts like the server in centralized learning, handling both model and control variate updates.
Due to the complete decentralization of the enviroment, a global model is also maintained in the aggregator. This consumes additional bandwidth.
::todo:: Improve efficiency by estimating the global model.
