Abstract
Disclosed herein is a technique for operating a navigation server and a plurality of navigation clients. Each of the navigation clients transmits a model data trained on a local training data set to the navigation server. The navigation client also transmits attribute data characterizing the local training data set to the navigation server. The navigation server uses the attribute data to weigh the contributions of the model data for performing a weighted aggregation into an aggregated set of model parameters for distribution to the navigation client for improving its local model data.
