ELU

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

Applies the element-wise function:

ELU(x)={x, if x>0α(exp(x)1), if x0\text{ELU}(x) = \begin{cases} x, & \text{ if } x > 0\\ \alpha * (\exp(x) - 1), & \text{ if } x \leq 0 \end{cases}
Parameters
  • alpha – the α\alpha value for the ELU formulation. Default: 1.0
  • inplace – can optionally do the operation in-place. Default: False
Shape:
  • Input: (N,)(N, *) where * means, any number of additional dimensions
  • Output: (N,)(N, *) , same shape as the input

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