#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\`.
