Sigmoid module
Applies the element-wise function:
nn_sigmoid()
\mbox{Sigmoid}(x) = σ(x) = \frac{1}{1 + \exp(-x)}
Input: (N, *) where * means, any number of additional
dimensions
Output: (N, *), same shape as the input
if (torch_is_installed()) {
m <- nn_sigmoid()
input <- torch_randn(2)
output <- m(input)
}Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
