java.lang.Object

org.deeplearning4j.nn.updater.MultiLayerUpdater

All Implemented Interfaces:

Serializable, Cloneable, Updater

public class MultiLayerUpdater
extends Object
implements Updater

MultiLayerUpdater: Gradient updater for MultiLayerNetworks. Expects backprop gradients for all layers to be in single Gradient object, keyed by "0_b", "1_w" etc., as per MultiLayerNetwork.backward()

Method Detail

update

public void update(Layer layer,
                   Gradient gradient,
                   int iteration,
                   int batchSize)

Description copied from interface: Updater

Updater: updates the model

Specified by:

update in interface Updater

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)

Specified by:

getAggregator in interface Updater

Parameters:

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

clone

public Updater clone()

Specified by:

clone in interface Updater

Overrides:

clone in class Object
