Field Detail

depthMultiplier

protected int depthMultiplier

Set channels multiplier of channels-wise step in separable convolution

dataFormat

protected CNN2DFormat dataFormat

pointWiseConstraints

protected List<LayerConstraint> pointWiseConstraints

Set constraints to be applied to the point-wise convolution 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.
