# Hardswish¶

class torch.nn.Hardswish(inplace=False)[source]

Applies the hardswish function, element-wise, as described in the paper:

$\text{Hardswish}(x) = \begin{cases} 0 & \text{if~} x \le -3, \\ x & \text{if~} x \ge +3, \\ x \cdot (x + 3) /6 & \text{otherwise} \end{cases}$
Parameters

inplace – can optionally do the operation in-place. Default: False

Shape:
• Input: $(*)$, where $*$ means any number of dimensions.

• Output: $(*)$, same shape as the input.

Examples:

>>> m = nn.Hardswish()
>>> input = torch.randn(2)
>>> output = m(input)
