SparseAccumulatorTakeGradient

public final class SparseAccumulatorTakeGradient

Extracts the average sparse gradient in a SparseConditionalAccumulator.

The op will blocks until sufficient (i.e., more than num_required) gradients have been accumulated. If the accumulator has already aggregated more than num_required gradients, it will return its average of the accumulated gradients. Also automatically increments the recorded global_step in the accumulator by 1, and resets the aggregate to 0.

Constants

String OP_NAME The name of this op, as known by TensorFlow core engine

Public Methods

public static SparseAccumulatorTakeGradient<T> create (Scope scope, Operand<TString> handle, Operand<TInt32> numRequired, Class<T> dtype)

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

Parameters

handle The handle to a SparseConditionalAccumulator.
numRequired Number of gradients required before we return an aggregate.
dtype The data type of accumulated gradients. Needs to correspond to the type of the accumulator.
Returns
  • a new instance of SparseAccumulatorTakeGradient

public Output<TInt64> indices ()

Indices of the average of the accumulated sparse gradients.

public Output<TInt64> shape ()

Shape of the average of the accumulated sparse gradients.

public Output<T> values ()

Values of the average of the accumulated sparse gradients.
