ELU

class torch.nn.ELU(alpha: float = 1.0, inplace: bool = False)

Applies the element-wise function:

$\text{ELU}(x) = \max(0,x) + \min(0, \alpha * (\exp(x) - 1))$

Parameters

• alpha – the $\alpha$ value for the ELU formulation. Default: 1.0

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

Shape:

• Input: $(N, *)$ where * means, any number of additional dimensions

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

Examples:

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