# tensorflow::ops::Selu Class Reference

# tensorflow::ops::Selu

`#include <nn_ops.h>`

Computes scaled exponential linear: `scale * alpha * (exp(features) - 1)`

## Summary

if \< 0, `scale * features` otherwise.

To be used together with \`initializer = tf.variance_scaling_initializer(factor=1.0, mode='FAN_IN')`. For correct dropout, use`tf.contrib.nn.alpha_dropout\`.

See [Self-Normalizing Neural Networks](https://arxiv.org/abs/1706.02515)

Arguments:

- scope: A [Scope](https://www.tensorflow.org/versions/r2.3/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object

<br />

Returns:

- `https://www.tensorflow.org/versions/r2.3/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output`: The activations tensor.
