torch.nn.functional.hardsigmoid(input, inplace=False)[source][source]¶

Apply the Hardsigmoid function element-wise.

Hardsigmoid(x)={0if x≤−3,1if x≥+3,x/6+1/2otherwise\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}

Parameters

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

Return type

Tensor
