Tanhshrink¶

class paddle.nn. Tanhshrink ( name=None ) [source]

Tanhshrink Activation

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

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

Shape:

input: Tensor with any shape.
output: Tensor with the same shape as input.

Examples

           >>> import paddle

>>> x = paddle.to_tensor([-0.4, -0.2, 0.1, 0.3])
>>> m = paddle.nn.Tanhshrink()
>>> out = m(x)
>>> print(out)
Tensor(shape=[4], dtype=float32, place=Place(cpu), stop_gradient=True,
[-0.02005100, -0.00262472,  0.00033201,  0.00868741])
