Applies the element-wise function:

Usage

nn_hardsigmoid()

Details

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

Shape

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

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

Examples

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