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.

Navigation system

A method of determining a parking route for a vehicle travelling on a road network within a geographic area is disclosed. A sub-network is determined comprising a subset of segments of an electronic map that are representative of roads within a predetermined walking time or distance of a destination location. Data indicative of a walking time or distance from the segment to the destination location is associated, at least with the segments of the sub-network representing roads having at least one associated parking space. A search algorithm having an associated cost function is used to explore the segments of the sub-network from an origin location to identify a plurality of candidate parking routes, wherein the cost for a given parking route is based on the probability of the vehicle successfully finding a parking space on the parking route and the expected cumulative travel and walking time or distance to the destination location should a parking space be found along the parking route.
