ELU

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

ELU Activation.

\[\begin{split}ELU(x) = max(0, x) + min(0, \\alpha * (e^{x}-1))\end{split}\]
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 )
