Hardsigmoid module

Usage

nn_hardsigmoid()

Details

$$\text{Hardsigmoid}(x)=\{\begin{array}{ll}0& \text{if~}x\le -3,\\ 1& \text{if~}x\ge +3,\\ x/6+1/2& \text{otherwise}\end{array}$$

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_hardsigmoid()
input <- torch_randn(2)
output <- m(input)
}
