Tanh

class torch.nn.Tanh [source]

Applies the element-wise function:

$$\text{Tanh}(x) = \tanh(x) = \frac{\exp(x) - \exp(-x)} {\exp(x) + \exp(-x)}$$

Shape:

• Input: $(N, *)$ where * means, any number of additional dimensions
• Output: $(N, *)$ , same shape as the input

Examples:

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