Versioned name: Selu-1
Category: Arithmetic unary operation
Short description: Selu calculates the SELU activation function (https://arxiv.org/abs/1706.02515) element-wise with given tensor.
Detailed Description
For each element from the input tensor calculates corresponding element in the output tensor with the following formula:
![\[ selu(x) = \lambda \left\{\begin{array}{ll} \alpha(e^{x} - 1) \quad \mbox{if } x \le 0 \\ x \quad \mbox{if } x > 0 \end{array}\right. \]](form_121.png)
