Tanh

class torch.nn.Tanh(*args, **kwargs)

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.

Examples:

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