Method Detail

resetLayerDefaultConfig

public void resetLayerDefaultConfig()

Reset the learning related configs of the layer to default. When instantiated with a global neural network configuration the parameters specified in the neural network configuration will be used. For internal use with the transfer learning API. Users should not have to call this method directly.

Overrides:

resetLayerDefaultConfig in class Layer

clone

public BaseLayer clone()

Overrides:

clone in class Layer

getUpdaterByParam

public org.nd4j.linalg.learning.config.IUpdater getUpdaterByParam(String paramName)

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

Overrides:

getUpdaterByParam in class Layer

Parameters:

paramName - Parameter name

Returns:

IUpdater for the parameter
