Description

Applies the element-wise function:

Usage

nn_tanh()

Shape

• Input: $(N,\ast )$ where * means, any number of additional dimensions

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

Details

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

Examples

# NOT RUN {
if (torch_is_installed()) {
m <- nn_tanh()
input <- torch_randn(2)
output <- m(input)

}
# }
