Method Detail

opType

public Op.Type opType()

Description copied from class: DifferentialFunction

The type of the op

Overrides:

opType in class DifferentialFunction

Returns:

getOpType

public Op.Type getOpType()

Specified by:

getOpType in interface ReduceOp

resultType

public DataType resultType()

Description copied from interface: ReduceOp

This method returns datatype for result array wrt given inputs

Specified by:

resultType in interface ReduceOp

Returns:

resultType

public DataType resultType(OpContext oc)

Specified by:

resultType in interface ReduceOp

validateDataTypes

public boolean validateDataTypes(OpContext oc)

Specified by:

validateDataTypes in interface ReduceOp

dimensions

public INDArray dimensions()

Description copied from interface: ReduceOp

This method returns dimensions for this op

Specified by:

dimensions in interface ReduceOp

Overrides:

dimensions in class BaseOp

Returns:

calculateOutputShape

public List<LongShapeDescriptor> calculateOutputShape()

Description copied from class: DifferentialFunction

Calculate the output shape for this op

Specified by:

calculateOutputShape in class BaseReduceOp

Returns:

List of output shape descriptors

calculateOutputShape

public List<LongShapeDescriptor> calculateOutputShape(OpContext oc)

Overrides:

calculateOutputShape in class DifferentialFunction

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 DifferentialFunction

Parameters:

dataTypes - The data types of the inputs

Returns:

The data types of the outputs
