Newton-type methods are popular in federated learning due to their fast
convergence. Still, they suffer from two main issues, namely: low communication
efficiency and low privacy due to the requirement of sending Hessian
information from clients to parameter server (PS). In this work, we introduced
a novel framework called FedNew in which there is no need to transmit Hessian
information from clients to PS, hence resolving the bottleneck to improve
communication efficiency. In addition, FedNew hides the gradient information
and …
