Sigmoid module

Usage

nn_sigmoid()

Details

$$\text{Sigmoid}(x)=\sigma (x)=\frac{1}{1+\exp (-x)}$$

Shape

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

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

Examples

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