# tensorflow::ops::Sigmoid

`#include <math_ops.h>`

Computes sigmoid of `x` element-wise.

## Summary

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

Arguments:

- scope: A [Scope](https://www.tensorflow.org/versions/r1.15/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object

<br />

Returns:

- `https://www.tensorflow.org/versions/r1.15/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output`: The y tensor.
