Method Detail

preProcess

public org.nd4j.linalg.api.ndarray.INDArray preProcess(org.nd4j.linalg.api.ndarray.INDArray input,
                                                       int miniBatchSize)

Description copied from interface: InputPreProcessor

Pre preProcess input/activations for a multi layer network

Specified by:

preProcess in interface InputPreProcessor

Parameters:

input - the input to pre preProcess

Returns:

the processed input

backprop

public org.nd4j.linalg.api.ndarray.INDArray backprop(org.nd4j.linalg.api.ndarray.INDArray output,
                                                     int miniBatchSize)

Description copied from interface: InputPreProcessor

Reverse the preProcess during backprop. Process Gradient/epsilons before passing them to the layer below.

Specified by:

backprop in interface InputPreProcessor

Parameters:

output - which is a pair of the gradient and epsilon

Returns:

the reverse of the pre preProcess step (if any)

clone

public InputPreProcessor clone()

Specified by:

clone in interface InputPreProcessor

Overrides:

clone in class java.lang.Object

getOutputType

public InputType getOutputType(InputType inputType)

Description copied from interface: InputPreProcessor

For a given type of input to this preprocessor, what is the type of the output?

Specified by:

getOutputType in interface InputPreProcessor

Parameters:

inputType - Type of input for the preprocessor

Returns:

Type of input after applying the preprocessor
