Hardswish¶

class dragon.vm.torch.nn.Hardswish[source]¶

Apply the hard swish function. [Howard et.al, 2019].

The HardSwish function is defined as:

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

Examples:

m = torch.nn.Hardswish()
x = torch.randn(2, 3)
y = m(x)
