SparseConditionalAccumulator

public final class SparseConditionalAccumulator

A conditional accumulator for aggregating sparse 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.

Constant Value: "SparseConditionalAccumulator"

Public Methods

public Output<TString> asOutput ()

Returns the symbolic handle of the 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.

public static SparseConditionalAccumulator.Options container (String container)

Parameters

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

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

Factory method to create a class wrapping a new SparseConditionalAccumulator operation.

Parameters

scope	current scope
dtype	The type of the value being accumulated.
shape	The shape of the values.
options	carries optional attributes values

Returns

• a new instance of SparseConditionalAccumulator

public Output<TString> handle ()

The handle to the accumulator.

public static SparseConditionalAccumulator.Options reductionType (String reductionType)

public static SparseConditionalAccumulator.Options sharedName (String sharedName)

Parameters

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