Method Detail

constrainRecurrent

public T constrainRecurrent(LayerConstraint... constraints)

Set constraints to be applied to the RNN recurrent weight parameters of this layer. Default: no constraints.
Constraints can be used to enforce certain conditions (non-negativity of parameters, max-norm regularization, etc). These constraints are applied at each iteration, after the parameters have been updated.

Parameters:

constraints - Constraints to apply to the recurrent weight parameters of this layer

constrainInputWeights

public T constrainInputWeights(LayerConstraint... constraints)

Set constraints to be applied to the RNN input weight parameters of this layer. Default: no constraints.
Constraints can be used to enforce certain conditions (non-negativity of parameters, max-norm regularization, etc). These constraints are applied at each iteration, after the parameters have been updated.

Parameters:

constraints - Constraints to apply to the input weight parameters of this layer

weightInitRecurrent

public T weightInitRecurrent(WeightInit weightInit)

Set the weight initialization for the recurrent weights. Not that if this is not set explicitly, the same weight initialization as the layer input weights is also used for the recurrent weights.

Parameters:

weightInit - Weight initialization for the recurrent weights only.

weightInitRecurrent

public T weightInitRecurrent(Distribution dist)

Set the weight initialization for the recurrent weights, based on the specified distribution. Not that if this is not set explicitly, the same weight initialization as the layer input weights is also used for the recurrent weights.

Parameters:

dist - Distribution to use for initializing the recurrent weights
