CELU

class torch.nn.CELU(alpha=1.0, inplace=False)[source]

Applies the element-wise function:

CELU(x)=max(0,x)+min(0,α(exp(x/α)1))\text{CELU}(x) = \max(0,x) + \min(0, \alpha * (\exp(x/\alpha) - 1))

More details can be found in the paper Continuously Differentiable Exponential Linear Units .

Parameters:
  • alpha (float) – the α\alpha value for the CELU formulation. Default: 1.0

  • inplace (bool) – can optionally do the operation in-place. Default: False

Shape:
  • Input: ()(*), where * means any number of dimensions.

  • Output: ()(*), same shape as the input.

>>> m = nn.CELU()
>>> input = torch.randn(2)
>>> output = m(input)
