softsign¶

paddle.nn.functional. softsign ( x, name=None ) ¶

softsign激活函数

\[out = \frac{x}{1 + |x|}\]

参数：

x (Variable) - 张量（Tensor）
name (str|None) - 该层名称（可选）。若设为None，则自动为该层命名。

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.softsign(data)
