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 (Union[Array, ndarray, bool_, number, bool, int, float, complex]) – input array
alpha (Union[Array, ndarray, bool_, number, bool, int, float, complex]) – scalar or array of alpha values (default: 1.0)
- Return type:
Array
- Returns:
An array.
