See the guide: Neural Network > Activation Functions

Computes sigmoid of x element-wise.

Specifically, y = 1 / (1 + exp(-x)).

Args:

  • x: A Tensor with type float16, float32, float64, complex64, or complex128.
  • name: A name for the operation (optional).

Returns:

A Tensor with the same type as x.
