hard_shrink

.. py:function:: paddle.fluid.layers.hard_shrink(x,threshold=None)

HardShrink激活函数(HardShrink activation operator)

out = \begin{cases}
      x, \text{if } x > \lambda \\
      x, \text{if } x < -\lambda \\
      0,  \text{otherwise}
    \end{cases}

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)
