Class AccumulatorTakeGradient<T>

java.lang.Object

org.tensorflow.op.PrimitiveOp

org.tensorflow.op.core.AccumulatorTakeGradient<T>

Type Parameters:

T - data type for average() output

All Implemented Interfaces:

Op, Operand<T>

@Operator
public final class AccumulatorTakeGradient<T>
extends PrimitiveOp
implements Operand<T>

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.

Method Detail

create

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

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

Parameters:

scope - current graph 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

average

public Output<T> average()

The average of the accumulated gradients.

asOutput

public Output<T> 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<T>
