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¶

class Sigmoid : public ngraph::op::Op, public ngraph::op::util::UnaryElementwiseArithmetic
