LogSigmoid

class torch.nn.LogSigmoid(*args, **kwargs)[source]

Applies the element-wise function:

LogSigmoid(x)=log(11+exp(x))\text{LogSigmoid}(x) = \log\left(\frac{ 1 }{ 1 + \exp(-x)}\right)
Shape:
  • Input: ()(*), where * means any number of dimensions.

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

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