mindspore.mint.nn.Hardswish

class mindspore.mint.nn.Hardswish

Applies the Hard Swish activation function element-wise.

Hard Swish is defined as:

\[\begin{split}\text{Hardswish}(input) = \begin{cases} 0, & \text{ if } input \leq -3, \\ input, & \text{ if } input \geq +3, \\ input*(input + 3)/6, & \text{ otherwise } \end{cases}\end{split}\]

Inputs:

• input (Tensor) - The input tensor to be processed by Hard Swish.

Outputs:

Tensor, with the same type and shape as the input.

Supported Platforms:

Ascend

Examples

>>> import mindspore
>>> import numpy as np
>>> input = mindspore.Tensor(np.array([-1, -2, 0, 2, 1]), mindspore.float16)
>>> hswish = mindspore.mint.nn.Hardswish()
>>> result = hswish(input)
>>> print(result)
