Elu

`
#include <nn_ops.h>
`


Computes the exponential linear function.

## Summary


The ELU function is defined as:


- $ e \^ x - 1 $ if $ x \< 0 $
- $ x $ if $ x \>= 0 $

<br />


Examples:


tf.nn.elu(1.0)
tf.nn.elu(0.0) tf.nn.elu(-1000.0)

Args:

- scope: A [Scope](https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object

<br />


Returns:

- `

  ` : The activations tensor.
