|
||
GLU 激活层(GLU Activation Operator) | ||
|
||
门控线性单元。输入按照给定的维度二等分,其中第一部分被用作内容,第二部分经过一个 sigmoid 函数之后被用作门限。输出是内容和门限的逐元素乘积。更多细节请参考 `Language Modeling with Gated Convolutional Networks <https://arxiv.org/abs/1612.08083>`_ 。 | ||
|
||
.. math:: | ||
\mathrm{GLU}(a, b) = a \otimes \sigma(b) | ||
|
||
参数 | ||
:::::::::: | ||
- **axis** (int,可选) - 沿着该轴将输入二等分。:math:`D` 为输入的维数,则 :attr:`axis` 应该在 :math:`[-D, D)` 的范围内。如 :attr:`axis` 为负数,则相当于 :math:`axis + D`,默认值为-1。 | ||
- **name** (str,可选) - 具体用法请参见 :ref:`api_guide_Name`,一般无需设置,默认值为 None。 | ||
|
||
形状 | ||
:::::::::: | ||
- input:shape[axis]为偶数的 Tensor。 | ||
- output: 数据类型与输入一致,在指定的轴上其尺寸减半的 Tensor。 | ||

这个nn.GLU是一个layer,定义这个layer的时候应该是不用放输入的吧,我看其他激活函数也没有放输入
