Versioned name: Sigmoid-1
Category: Activation function
Short description: Sigmoid element-wise activation function.
Detailed description: Reference
Attributes: Sigmoid operation has no attributes.
Mathematical Formulation
For each element from the input tensor calculates corresponding element in the output tensor with the following formula:
\[sigmoid( x ) = \frac{1}{1+e^{-x}}\]
Inputs:
1: Input tensor x of any floating-point type. Required.
Outputs:
1: Result of Sigmoid function applied to the input tensor x. Floating-point tensor with shape and type matching the input tensor.
