Class ConditionalAccumulator

java.lang.Object

org.tensorflow.op.PrimitiveOp

org.tensorflow.op.core.ConditionalAccumulator

All Implemented Interfaces:

Op, Operand<String>

@Operator
public final class ConditionalAccumulator
extends PrimitiveOp
implements Operand<String>

A conditional accumulator for aggregating gradients.

The accumulator accepts gradients marked with local_step greater or equal to the most recent global_step known to the accumulator. The average can be extracted from the accumulator, provided sufficient gradients have been accumulated. Extracting the average automatically resets the aggregate to 0, and increments the global_step recorded by the accumulator.

Method Detail

create

public static <T> ConditionalAccumulator create(Scope scope,
                                                Class<T> dtype,
                                                Shape shape,
                                                ConditionalAccumulator.Options... options)

Factory method to create a class to wrap a new ConditionalAccumulator operation to the graph.

Parameters:

scope - current graph scope

dtype - The type of the value being accumulated.

shape - The shape of the values, can be [], in which case shape is unknown.

options - carries optional attributes values

Returns:

a new instance of ConditionalAccumulator

container

public static ConditionalAccumulator.Options container(String container)

Parameters:

container - If non-empty, this accumulator is placed in the given container. Otherwise, a default container is used.

sharedName

public static ConditionalAccumulator.Options sharedName(String sharedName)

Parameters:

sharedName - If non-empty, this accumulator will be shared under the given name across multiple sessions.

reductionType

public static ConditionalAccumulator.Options reductionType(String reductionType)

Parameters:

reductionType -

handle

public Output<String> handle()

The handle to the accumulator.

asOutput

public Output<String> asOutput()

Description copied from interface: Operand

Returns the symbolic handle of a tensor.

Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is used to obtain a symbolic handle that represents the computation of the input.

Specified by:

asOutput in interface Operand<String>
