hard_shrink¶
HardShrink激活函数(HardShrink activation operator)
\[\begin{split}out = \begin{cases} x, \text{if } x > \lambda \\ x, \text{if } x < -\lambda \\ 0, \text{otherwise} \end{cases}\end{split}\]
- 参数：
-
x - HardShrink激活函数的输入
threshold (FLOAT)-HardShrink激活函数的threshold值。[默认：0.5]
返回：HardShrink激活函数的输出
代码示例：
import paddle.fluid as fluid
data = fluid.layers.data(name="input", shape=[784])
result = fluid.layers.hard_shrink(x=data, threshold=0.3)
