oneflow.softplus

oneflow.softplus(x: Tensor, beta: double = 1, threshold: double = 20)Tensor

Applies the element-wise function:

\[\text{Softplus}(x) = \frac{1}{\beta} * \log(1 + \exp(\beta * x))\]

For numerical stability the implementation reverts to the linear function when \(input \times \beta > threshold\).

See Softplus for more details.
