Method Detail

preProcess

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

Pre preProcess input/activations for a multi layer network

Parameters:

input - the input to pre preProcess

miniBatchSize -

Returns:

the processed input

backprop

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

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

Parameters:

output - which is a pair of the gradient and epsilon

miniBatchSize -

Returns:

the reverse of the pre preProcess step (if any)

clone

InputPreProcessor clone()

getOutputType

InputType getOutputType(InputType inputType)

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

Parameters:

inputType - Type of input for the preprocessor

Returns:

Type of input after applying the preprocessor
