Sigmoid

Sigmoid  // Elementwise sigmoid operation

Description

Produces a single output tensor of the same element type and shape as arg, where the value at each coordinate of output is the sigmoid of arg at the same coordinate.

Inputs

Name Element Type Shape
arg Any Any

Outputs

Name Element Type Shape
output Same as arg Same as arg

Mathematical Definition

\[\mathtt{output}_{i_0, \ldots, i_{n-1}} = \frac{1}{1+\exp(-\mathtt{arg}_{i_0, \ldots, i_{n-1}})}\]

C++ Interface
