paddle.fluid / layers / softplus
softplus¶
-
paddle.nn.functional.softplus( x, name=None ) ¶
softplus激活函数
\[out = \ln(1 + e^{x})\]
- 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.softplus(data)
