dragon.vm.torch.nn.functional.hardswish(input)[source]¶

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

The HardSwish function is defined as:

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

Parameters:

• input (dragon.vm.torch.Tensor) – The input tensor.

Returns:

dragon.vm.torch.Tensor – The output tensor.
