Selu

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: \f[ 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. \f]

Attributes:

No attributes available.

Inputs

  • 1: An tensor of type T. Required.

  • 2: alpha 1D tensor with one element of type T. Required.

  • 3: lambda 1D tensor with one element of type T. Required.

Outputs

  • 1: The result of element-wise operation. A tensor of type T.

Types

  • T: any supported floating point type.
