.. py:function:: paddle.fluid.layers.softshrink(x, alpha=None)
Softshrink激活函数
out = \begin{cases} x - \alpha, \text{if } x > \alpha \\ x + \alpha, \text{if } x < -\alpha \\ 0, \text{otherwise} \end{cases}
- 参数:
- x (Variable0 - 张量(Tensor)
- alpha (float) - 上面公式中alpha的值
返回: 张量(Tensor)
返回类型: 变量(Variable)
代码示例:
import paddle.fluid as fluid
data = fluid.layers.data(name="input", shape=[32, 784])
result = fluid.layers.softshrink(data)
