Softsign

class torch.nn.Softsign

Applies the element-wise function:

$$\text{SoftSign}(x) = \frac{x}{ 1 + |x|}$$

Shape:

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

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

Examples:

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