torch：hardsigmoid

hardsigmoid

torch.nn.functional.hardsigmoid(input) → Tensor[SOURCE]

Applies the element-wise function

\text{Hardsigmoid}(x) = \begin{cases} 0 & \text{if~} x \le -3, \\ 1 & \text{if~} x \ge +3, \\ x / 6 + 1 / 2 & \text{otherwise} \end{cases}Hardsigmoid(x)=⎩⎪⎪⎨⎪⎪⎧​01x/6+1/2​if x≤−3,if x≥+3,otherwise​

Parameters

inplace – If set to True, will do this operation in-place. Default: False
