Mish

class paddle.nn. Mish ( name=None ) [source]

Mish Activation.

\[ \begin{align}\begin{aligned}\begin{split}softplus(x) = \begin{cases} x, \text{if } x > \text{threshold} \\ \ln(1 + e^{x}), \text{otherwise} \end{cases}\end{split}\\Mish(x) = x * \tanh(softplus(x))\end{aligned}\end{align} \]
Parameters

name (str, optional) – Name for the operation (optional, default is None). For more information, please refer to Name.

Shape:

  • input: Tensor with any shape.

  • output: Tensor with the same shape as input.

Examples

import paddle

x = paddle.to_tensor([-5., 0., 5.])
m = paddle.nn.Mish()
out = m(x) # [-0.03357624, 0., 4.99955208]
forward ( x )
