class brainstate.nn.celu(x, alpha=1.0)[source]#

Continuously-differentiable Exponential Linear Unit activation.

Computes the element-wise function:

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

  • x (Array | ndarray | bool | number | bool | int | float | complex | Quantity) – Input array.

  • alpha (Array | ndarray | bool | number | bool | int | float | complex | Quantity) – Scalar or array value controlling the smoothness. Default is 1.0.

Returns:

An array with the same shape as the input.

Return type:

Array | Quantity
