Description

Applies the element-wise function:

Usage

nn_sigmoid()

Shape

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

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

Details

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

Examples

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

}
# }
