Negative

Negative  //  Elementwise negative 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 negative of the value at each arg coordinate.

Inputs

Name Element Type Shape
arg Any Any

Outputs

Name Element Type Shape
output Same as arg Same as arg

Mathematical Definition

\[\mathtt{output}_{i_0, \ldots, i_{n-1}} = -\mathtt{arg}_{i_0, \ldots, i_{n-1}}\]

Backprop

\[\overline{\mathtt{arg}} \leftarrow -\Delta\]

C++ Interface

class Negative : public ngraph::op::util::UnaryElementwiseArithmetic

Elementwise negative operation.

Public Functions

const std::string &description() const

Get the string name for the type of the node, such as Add or Multiply. The class name, must not contain spaces as it is used for codegen.

Return
A const reference to the node’s type name

Negative()

Constructs a negative operation.

Negative(const Output<Node> &arg)

Constructs a negative operation.

Parameters
  • arg: Node that produces the input tensor.
