paddle.fluid / layers / logsigmoid

logsigmoid¶

paddle.fluid.layers. logsigmoid ( x, name=None ) ¶

Logsigmoid激活函数

\[out = \log \frac{1}{1 + e^{-x}}\]

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.logsigmoid(data)
