celu

paddle.nn.functional. celu ( x, alpha=1.0, name=None ) [source]

celu activation.

\[celu(x) = max(0, x) + min(0, \alpha * (e^{x/\alpha}-1))\]
Parameters
  • x (Tensor) – The input Tensor with data type float32, float64.

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

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

Returns

A Tensor with the same data type and shape as x .

Examples

import paddle
import paddle.nn.functional as F
x = paddle.to_tensor([[-1., 6.], [1., 15.6]])
out = F.celu(x, alpha=0.2)
# [[-0.19865242,  6.        ],
#  [ 1.        , 15.60000038]]
