tanh | ||
------------------------------- | ||
|
||
.. py:function:: paddle.nn.function.tanh(x, name=None) | ||
tanh 激活函数 | ||
|
||
.. math:: | ||
out = \frac{e^{x} - e^{-x}}{e^{x} + e^{-x}} | ||
参数: | ||
|
||
- **x** (Tensor) - Tanh算子的输入, 多维Tensor,数据类型为 float16,float32或float64。 | ||
- **name** (str, 可选) - 该层名称(可选,默认为None)。具体用法请参见 :ref:`api_guide_Name`。 | ||
|
||
返回: tanh的输出Tensor,和输入有着相同类型和shape。 | ||
|
||
返回类型: Tensor | ||
|
||
**代码示例**: | ||
|
||
.. code-block:: python | ||
import numpy as np | ||
import paddle | ||
import paddle.nn.function as F | ||
paddle.disable_static() | ||
x_data = np.array([-0.4, -0.2, 0.1, 0.3]) | ||
x = paddle.to_tensor(x_data) | ||
out = F.tanh(x) | ||
print(out.numpy()) | ||
# [-0.37994896 -0.19737532 0.09966799 0.29131261] | ||

.. py:function:: paddle.tensor.math.sign(x, name=None) | ||
此OP对输入x中每个元素进行正负判断,并且输出正负判断值:1代表正,-1代表负,0代表零。 | ||
|
||
参数: | ||
- **x** (Tensor) – 进行正负值判断的多维Tensor,数据类型为 float16, float32或float64。 | ||
- **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。 | ||
|
||
返回:输出正负号Tensor,数据的shape大小及数据类型和输入 ``x`` 一致。 | ||
|
||
返回类型:Tensor | ||
|
||
**代码示例** | ||
|
||
.. code-block:: python | ||
import numpy as np | ||
import paddle | ||
data = np.array([3.0, 0.0, -2.0, 1.7], dtype='float32') | ||
paddle.disable_static() | ||
x = paddle.to_tensor(data) | ||
out = paddle.tensor.math.sign(x=x) | ||
print(out) # [1.0, 0.0, -1.0, 1.0] | ||
