mindspore.nn.HSigmoid

class mindspore.nn.HSigmoid

Applies Hard sigmoid activation function element-wise.

Hard sigmoid is defined as:

$$\text{hsigmoid}(x_i)=max(0,min(1,\frac{x_i+3}{6})),$$

HSigmoid Activation Function Graph:

Inputs:

• input_x (Tensor) - The input of HSigmoid. Tensor of any dimension.

Outputs:

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

Raises

TypeError – If input_x is not a Tensor.

Supported Platforms:

Ascend GPU CPU

Examples

>>> import mindspore
>>> from mindspore import Tensor, nn
>>> import numpy as np
>>> x = Tensor(np.array([-1, -2, 0, 2, 1]), mindspore.float16)
>>> hsigmoid = nn.HSigmoid()
>>> result = hsigmoid(x)
>>> print(result)
