getAggregator

public UpdaterAggregator getAggregator(boolean addThis)

Description copied from interface: Updater

Given this updater, get an UpdaterAggregator that can be used to combine the current state (if any) of this updater with the state of other updaters. Typically used only in distributed learning scenarios (where each copy of the network has an updater that needs to be combined)

Parameters:

addThis - whether to add the Updater to the UpdaterAggregator, or just return an empy aggregator
