tf.raw_ops.SigmoidGrad

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

tf.raw_ops.SigmoidGrad(
    y, dy, name=None
)

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

y A Tensor. Must be one of the following types: bfloat16, half, float32, float64, complex64, complex128.
dy A Tensor. Must have the same type as y.
name A name for the operation (optional).

A Tensor. Has the same type as y.
