Silu¶

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

Silu Activation

\[silu(x) = \frac{x}{1 + \mathrm{e}^{-x}}\]

Where \(x\) is the input Tensor.

Parameters: name (str, optional) – For details, please refer to Name. Generally, no setting is required. Default: None.

Shape:

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

Examples

           >>> import paddle

>>> x = paddle.to_tensor([1.0, 2.0, 3.0, 4.0])
>>> m = paddle.nn.Silu()
>>> out = m(x)
>>> print(out)
Tensor(shape=[4], dtype=float32, place=Place(cpu), stop_gradient=True,
[0.73105860, 1.76159406, 2.85772228, 3.92805505])

          

forward ( x ) forward¶

Defines the computation performed at every call. Should be overridden by all subclasses.

Parameters

*inputs (tuple) – unpacked tuple arguments
**kwargs (dict) – unpacked dict arguments

extra_repr ( ) extra_repr¶: Extra representation of this layer, you can have custom implementation of your own layer.
