ncdl.nn.Tanh

class ncdl.nn.Tanh(*args: Any, **kwargs: Any)

Applies the Hyperbolic Tangent (Tanh) function element-wise.

Tanh is defined as:

\[\text{Tanh}(x) = \tanh(x) = \frac{\exp(x) - \exp(-x)} {\exp(x) + \exp(-x)}\]
Shape:

  • Input: \((*)\), where \(*\) means any number of dimensions.

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

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