mindspore.ops.HShrink
- class mindspore.ops.HShrink(lambd=0.5)[source]
Applies the hard shrinkage function element-wise, each element complies with the following function:
\[\begin{split}\text{HardShrink}(x) = \begin{cases} x, & \text{ if } x > \lambda \\ x, & \text{ if } x < -\lambda \\ 0, & \text{ otherwise } \end{cases}\end{split}\]- Parameters
lambd (float) – The value for the HardShrink formulation. Default: 0.5
- Inputs:
input_x (Tensor) - The input of HardShrink with data type of float16 or float32.
- Outputs:
Tensor, the same shape and data type as the input.
- Supported Platforms:
Ascend
- Raises
Examples
>>> import mindspore as ms >>> import mindspore.ops as ops >>> from mindspore import Tensor, nn >>> import numpy as np >>> input_x = Tensor(np.array([[0.5, 1, 2.0], [0.0533, 0.0776, -2.1233]]), ms.float32) >>> hshrink = ops.HShrink() >>> output = hshrink(input_x) >>> print(output) [[ 0. 1. 2. ] [ 0. 0. -2.1233]]
