Method Detail

defineLayer

public SDVariable defineLayer(SameDiff SD,
                              SDVariable input,
                              Map<String,SDVariable> paramTable,
                              SDVariable mask)

Description copied from class: SameDiffLayer

Define the layer

Specified by:

defineLayer in class SameDiffLayer

Parameters:

SD - SameDiff instance

input - Input to the layer

paramTable - Parameter table - keys as defined by AbstractSameDiffLayer.defineParameters(SDLayerParams)

mask - Optional, maybe null. Mask to apply if supported

Returns:

The final layer variable corresponding to the activations/output from the forward pass

defineParameters

public void defineParameters(SDLayerParams params)

Description copied from class: AbstractSameDiffLayer

Define the parameters for the network. Use SDLayerParams.addWeightParam(String, long...) and SDLayerParams.addBiasParam(String, long...)

Specified by:

defineParameters in class AbstractSameDiffLayer

Parameters:

params - Object used to set parameters for this layer

initializeParameters

public void initializeParameters(Map<String,INDArray> params)

Description copied from class: AbstractSameDiffLayer

Set the initial parameter values for this layer, if required

Specified by:

initializeParameters in class AbstractSameDiffLayer

Parameters:

params - Parameter arrays that may be initialized

getOutputType

public InputType getOutputType(int layerIndex,
                               InputType inputType)

Description copied from class: Layer

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

Specified by:

getOutputType in class Layer

Parameters:

layerIndex - Index of the layer

inputType - Type of input for the layer

Returns:

Type of output from the layer

setNIn

public void setNIn(InputType inputType,
                   boolean override)

Description copied from class: Layer

Set the nIn value (number of inputs, or input channels for CNNs) based on the given input type

Overrides:

setNIn in class AbstractSameDiffLayer

Parameters:

inputType - Input type for this layer

override - If false: only set the nIn value if it's not already set. If true: set it regardless of whether it's already set or not.
