HardSigmoid

Versioned name: HardSigmoid-1

Category: Activation function

Short description: HardSigmoid element-wise activation function.

Attributes: HardSigmoid operation has no attributes.

Mathematical Formulation

For each element from the input tensor calculates corresponding element in the output tensor with the following formula: \f[ y = max(0, min(1, alpha * x + beta)) \f]

Inputs

• 1: An tensor of type T. Required.

• 2: alpha 0D tensor (scalar) of type T. Required.

• 3: beta 0D tensor (scalar) of type T. Required.

Outputs

• 1: The result of the hard sigmoid operation. A tensor of type T.

Types

• T: any floating point type.
