jax.nn.elu(x, alpha=1.0)

Exponential linear unit activation function.

Computes the element-wise function:

\[\begin{split}\mathrm{elu}(x) = \begin{cases} x, & x > 0\\ \alpha \left(\exp(x) - 1\right), & x \le 0 \end{cases}\end{split}\]

Parameters:

• x (jax.typing.ArrayLike) – input array

• alpha (jax.typing.ArrayLike) – scalar or array of alpha values (default: 1.0)

Returns:
