Versioned name: Elu-1
Category: Activation function
Short description: Exponential linear unit element-wise activation function.
Detailed Description
For each element from the input tensor calculates corresponding element in the output tensor with the following formula:
![\[ elu(x) = \left\{\begin{array}{ll} alpha(e^{x} - 1) \quad \mbox{if } x < 0 \\ x \quad \mbox{if } x \geq 0 \end{array}\right. \]](form_117.png)
Attributes
- alpha
- Description: scale for the negative factor
- Range of values: arbitrary floating point number
- Type: float
- Default value: none
- Required: yes
Inputs:
- 1: Input tensor x of any floating point type. Required.
Outputs:
- 1: Result of Elu function applied to the input tensor x. Floating point tensor with shape and type matching the input tensor. Required.
