ELU¶

class paddle.nn. ELU ( alpha=1.0, name=None ) [source]

ELU Activation.

\[\begin{split}ELU(x)= \left\{ \begin{array}{lcl} x,& &\text{if } \ x > 0 \\ alpha * (e^{x} - 1),& &\text{if } \ x <= 0 \end{array} \right.\end{split}\]

Parameters

• alpha (float, optional) – The ‘alpha’ value of the ELU formulation. Default is 1.0.

• 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([[-1. ,6.], [1., 15.6]])
m = paddle.nn.ELU(0.2)
out = m(x)
# [[-0.12642411  6.        ]
#  [ 1.          15.6      ]]

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
