Tanhshrink

class torch.nn.modules.activation.Tanhshrink(*args, **kwargs) [source]

Applies the element-wise Tanhshrink function.

Tanhshrink(x)=xtanh(x)\text{Tanhshrink}(x) = x - \tanh(x)
Shape:
  • Input: ()(*), where * means any number of dimensions.
  • Output: ()(*), same shape as the input.

>>> input = torch.randn(2)
>>> output = m(input)
forward(input) [source]

Runs the forward pass.
