paddle / tanh
tanh¶
tanh 激活函数
\[out = \frac{e^{x} - e^{-x}}{e^{x} + e^{-x}}\]
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 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：
import paddle
x = paddle.to_tensor([-0.4, -0.2, 0.1, 0.3])
y = paddle.tanh(x)
print(y) # y=[-0.37994900, -0.19737528, 0.09966799, 0.29131261]
