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.
| Args | |
|---|---|
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). |
| Returns | |
|---|---|
A Tensor. Has the same type as y. |
