torch (version 0.8.1)

nn_tanh: Tanh module

Description

Applies the element-wise function:

Usage

nn_tanh()

Shape

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

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

Details

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

Examples

if (torch_is_installed()) {
m <- nn_tanh()
input <- torch_randn(2)
output <- m(input)
}
