oneflow.nn.functional.selu

oneflow.nn.functional.selu(x: Tensor) → Tensor

Applies element-wise function

\[ext{SELU}(x) = scale * (\max(0,x) + \min(0, lpha * (\exp(x) - 1)))`, with :math:`lpha=1.6732632423543772848170429916717` and :math:`scale=1.0507009873554804934193349852946`.\]

See SELU for more details.

For examples:

>>> import numpy as np
>>> import oneflow as flow

>>> x = np.array([1, 2, 3]).astype(np.float32)
>>> input = flow.tensor(x)
>>> out = flow.nn.functional.selu(input)
>>> out
tensor([1.0507, 2.1014, 3.1521], dtype=oneflow.float32)
