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) – For details, please refer to Name. Generally, no setting is required. Default: None.

Returns

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

Examples

import paddle
import paddle.nn.functional as F

x = paddle.to_tensor([-0.4, -0.2, 0.1, 0.3])
out = F.tanhshrink(x)
print(out)
# Tensor(shape=[4], dtype=float32, place=Place(gpu:0), stop_gradient=True,
#        [-0.02005106, -0.00262468,  0.00033200,  0.00868741])
