Class SigmoidGrad<T extends TType>

java.lang.Object

org.tensorflow.op.RawOp

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

Type Parameters:

T - data type for z output

All Implemented Interfaces:

org.tensorflow.ndarray.Shaped, Op, Operand<T>

public final class SigmoidGrad<T extends TType>
extends RawOp
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.

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

Type Parameters:

T - data type for SigmoidGrad output and operands

Parameters:

scope - current scope

y - The y value

dy - The dy value

Returns:

a new instance of SigmoidGrad

z

public Output<T> z()

Gets z.

Returns:

z.

asOutput

public Output<T> asOutput()

Description copied from interface: Operand

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.

Specified by:

asOutput in interface Operand<T extends TType>
