mindspore.ops.silu
==================
.. py:function:: mindspore.ops.silu(x)
激活函数SiLUSigmoid Linear Unit
该激活函数定义为:
.. math::
\text{SiLU}(x) = x * \sigma(x),
其中 :math:`x_i` 是输入的元素, math:`\sigma(x)` Logistic Sigmoid函数。
.. math::
\text{sigma}(x_i) = \frac{1}{1 + \exp(-x_i)},
关于SiLU的图例见 `SiLU <https://en.wikipedia.org/wiki/Activation_function#/media/File:Swish.svg>`_
参数:
- **x** (Tensor) - 数据类型为float16, float32, float64, complex64 或 complex128的输入。任意维度的Tensor。
返回:
Tensor数据类型和shape与 `x` 的相同。
异常:
- **TypeError** - `x` 的数据类型不是float16, float32, float64, complex64 或 complex128。
