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 NodeTypeInfo &get_type_info() const

Returns the NodeTypeInfo for the node’s class. During transition to type_info, returns a dummy type_info for Node if the class has not been updated yet.

Negative()

Constructs a negative operation.

Negative(const Output<Node> &arg)

Constructs a negative operation.

Parameters
  • arg: Node that produces the input tensor.
