Method Detail

opName

public String opName()

Description copied from class: DynamicCustomOp

This method returns op opName as string

Specified by:

opName in interface CustomOp

Overrides:

opName in class DynamicCustomOp

Returns:

onnxName

public String onnxName()

Description copied from class: DifferentialFunction

The opName of this function in onnx

Overrides:

onnxName in class DynamicCustomOp

Returns:

tensorflowName

public String tensorflowName()

Description copied from class: DifferentialFunction

The opName of this function tensorflow

Overrides:

tensorflowName in class DynamicCustomOp

Returns:

generateFake

public INDArray generateFake(long... shape)

Description copied from class: DynamicCustomOp

Generate fake data for DynamicCustomOp.computeArrays() of the the given shape with the data type Nd4j.defaultFloatingPointType()

Overrides:

generateFake in class DynamicCustomOp

Parameters:

shape - the shape to use

Returns:

the generated data

generateFake

public INDArray generateFake(DataType dataType,
                             long... shape)

Description copied from class: DynamicCustomOp

Generate fake data for DynamicCustomOp.computeArrays() of the the given shape with the given data type

Overrides:

generateFake in class DynamicCustomOp

Parameters:

dataType - the data type of the output array

shape - the shape to use

Returns:

the generated data

doDiff

public List<SDVariable> doDiff(List<SDVariable> grad)

Description copied from class: DifferentialFunction

The actual implementation for automatic differentiation.

Overrides:

doDiff in class DynamicCustomOp

Returns:

calculateOutputDataTypes

public List<DataType> calculateOutputDataTypes(List<DataType> dataTypes)

Description copied from class: DifferentialFunction

Calculate the data types for the output arrays. Though datatypes can also be inferred from DifferentialFunction.calculateOutputShape(), this method differs in that it does not require the input arrays to be populated. This is important as it allows us to do greedy datatype inference for the entire net - even if arrays are not available.

Overrides:

calculateOutputDataTypes in class BaseDynamicTransformOp

Parameters:

dataTypes - The data types of the inputs

Returns:

The data types of the outputs
