Tanh#

classtorch.nn.modules.activation.Tanh(*args,**kwargs)[source]#

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

Tanh is defined as:

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

Shape:

• Input:$(\ast )$(∗), where$\ast$∗ means any number of dimensions.

• Output:$(\ast )$(∗), same shape as the input.

Examples:

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

forward(input)[source]#

Runs the forward pass.

Return type

Tensor
