Sigmoid

class torch.nn.Sigmoid[source]

Applies the element-wise function:

Sigmoid(x)=σ(x)=11+exp(x)\text{Sigmoid}(x) = \sigma(x) = \frac{1}{1 + \exp(-x)}
Shape:
  • Input: (N,)(N, *) where * means, any number of additional dimensions

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

Examples:

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