Sign¶

Sign  //  Elementwise sign operation


Description¶

Produces a tensor of the same element type and shape as arg, where the value at each coordinate of output is the sign (-1, 0, 1) of the value at the corresponding coordinate of arg.

Inputs¶

Name Element Type Shape
arg Any Any

Outputs¶

Name Element Type Shape
output Same as arg Same as arg

Mathematical Definition¶

$\mathtt{output}_{i_0, \ldots, i_{n-1}} = \mathtt{sgn}(\mathtt{arg}_{i_0, \ldots, i_{n-1}})$

C++ Interface¶

class Sign : public ngraph::op::util::UnaryElementwiseArithmetic

Elementwise sign operation.

Public Functions

Sign(const std::shared_ptr<Node> &arg)

Constructs an elementwise sign operation.

Parameters
• arg: Node that produces the input tensor.
