CELU

class paddle.nn. CELU ( alpha: float = 1.0, name: Optional[str] = None ) [source]

CELU Activation.

\[CELU(x) = max(0, x) + min(0, \alpha * (e^{x/\alpha}-1))\]

Parameters

alpha (float, optional) – The ‘alpha’ value of the CELU formulation. Default is 1.0.
name (str|None, optional) – Name for the operation (optional, default is None). For more information, please refer to api_guide_Name.

Shape:

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

Examples

           >>> import paddle

>>> x = paddle.to_tensor([[-1. ,6.], [1., 15.6]])
>>> m = paddle.nn.CELU(0.2)
>>> out = m(x)
>>> print(out)
Tensor(shape=[2, 2], dtype=float32, place=Place(cpu), stop_gradient=True,
[[-0.19865242,  6.        ],
 [ 1.        , 15.60000038]])

          

forward ( x: Tensor ) → Tensor 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 ( ) → str extra_repr¶: Extra representation of this layer, you can have custom implementation of your own layer.
