Method Details

init

public void init()

Description copied from class: AbstractLayer

This method should implement layer initialization in subclasses, when a layer is added to the network (create weights, outputs, deltas, randomization etc.).

Overrides:

init in class OutputLayer

initTransientFields

public void initTransientFields()

Overrides:

initTransientFields in class AbstractLayer<TensorBase,TensorBase,Tensor2D>

forward

public void forward()

This method implements forward pass for the output layer. Calculates layer outputs using softmax function

Specified by:

forward in interface Layer<TensorBase>

Overrides:

forward in class OutputLayer

backward

public void backward()

Performs backward pass for this layer.

Specified by:

backward in interface Layer<TensorBase>

Overrides:

backward in class OutputLayer
