tf.keras.activations.elu

tf.keras.activations.elu(
    x,
    alpha=1.0
)

Defined in tensorflow/python/keras/activations.py.

Exponential linear unit.

Arguments:

  • x: Input tensor.
  • alpha: A scalar, slope of negative section.

Returns:

The exponential linear activation: `x` if `x > 0` and
  `alpha * (exp(x)-1)` if `x < 0`.
