instantiate

public Layer instantiate(NeuralNetConfiguration conf,
                         Collection<TrainingListener> trainingListeners,
                         int layerIndex,
                         INDArray layerParamsView,
                         boolean initializeParams,
                         DataType networkDataType)

Specified by:

instantiate in class Layer

initializer

public ParamInitializer initializer()

Specified by:

initializer in class Layer

Returns:

The parameter initializer for this model

getUpdaterByParam

public IUpdater getUpdaterByParam(String paramName)

Description copied from class: BaseLayer

Get the updater for the given parameter. Typically the same updater will be used for all updaters, but this is not necessarily the case

Specified by:

getUpdaterByParam in interface TrainingConfig

Overrides:

getUpdaterByParam in class BaseLayer

Parameters:

paramName - Parameter name

Returns:

IUpdater for the parameter

getAlpha

public double getAlpha()

getLambda

public double getLambda()

getGradientCheck

public boolean getGradientCheck()

getMemoryReport

public LayerMemoryReport getMemoryReport(InputType inputType)

Description copied from class: Layer

This is a report of the estimated memory consumption for the given layer

Overrides:

getMemoryReport in class BaseOutputLayer

Parameters:

inputType - Input type to the layer. Memory consumption is often a function of the input type

Returns:

Memory report for the layer
