paddle.nn / Swish

Swish¶

class paddle.nn. Swish ( name=None ) [源代码] ¶

Swish激活层

\[Swish(x) = \frac{x}{1 + e^{-x}}\]

其中，\(x\) 为输入的 Tensor

参数¶

name (str, 可选) - 操作的名称(可选，默认值为None）。更多信息请参见 Name。

形状:¶

input: 任意形状的Tensor。

output: 和input具有相同形状的Tensor。

代码示例¶

import paddle
import numpy as np

x = paddle.to_tensor(np.array([-2., 0., 1.]))
m = paddle.nn.Swish()
out = m(x) # [-0.238406, 0., 0.731059]
