tanhshrink¶

paddle.nn.functional. tanhshrink ( x, name=None ) [source]

tanhshrink activation

\[tanhshrink(x) = x - tanh(x)\]

Parameters

• x (Tensor) – The input Tensor with data type float32, float64.

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

Returns

A Tensor with the same data type and shape as x .

Examples

import paddle
import paddle.nn.functional as F
import numpy as np

x = paddle.to_tensor(np.array([-0.4, -0.2, 0.1, 0.3]))
out = F.tanhshrink(x) # [-0.020051, -0.00262468, 0.000332005, 0.00868739]
