AccumulatorTakeGradient

public final class AccumulatorTakeGradient

Extracts the average gradient in the given ConditionalAccumulator.

The op 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 returns the 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

Output <T>
asOutput ()
Returns the symbolic handle of the tensor.
Output <T>
average ()
The average of the accumulated gradients.
static <T extends TType > AccumulatorTakeGradient <T>
create ( Scope scope, Operand < TString > handle, Operand < TInt32 > numRequired, Class<T> dtype)
Factory method to create a class wrapping a new AccumulatorTakeGradient operation.

Inherited Methods

Constants

public static final String OP_NAME

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

Constant Value: "AccumulatorTakeGradient"

Public Methods

public Output <T> 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 Output <T> average ()

The average of the accumulated gradients.

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

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

Parameters
scope current scope
handle The handle to an accumulator.
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 AccumulatorTakeGradient
