flax.linen.celu

flax.linen.celu(x, alpha=1.0)

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 – input array

• alpha – array or scalar (default: 1.0)
