Class SigmoidGrad<T>

java.lang.Object

org.tensorflow.op.PrimitiveOp

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

Type Parameters:

T - data type for z() output

All Implemented Interfaces:

Op, Operand<T>

public final class SigmoidGrad<T>
extends PrimitiveOp
implements Operand<T>

Computes the gradient of the sigmoid of `x` wrt its input.

Specifically, `grad = dy * y * (1 - y)`, where `y = sigmoid(x)`, and `dy` is the corresponding input gradient.

Method Detail

create

public static <T> SigmoidGrad<T> create(Scope scope,
                                        Operand<T> y,
                                        Operand<T> dy)

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

Parameters:

scope - current graph scope

y -

dy -

Returns:

a new instance of SigmoidGrad

z

public Output<T> z()

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>
