Add

Add  // Elementwise add operation

Description

Elementwise add operation.

Produces tensor of the same element type and shape as the two inputs, where the value at each coordinate of output is the sum of the values at the corresponding input coordinates.

Inputs

Name Element Type Shape
arg0 any any
arg1 same as arg0 same as arg0

Outputs

Name Element Type Shape
output same as arg0 same as arg0

Mathematical Definition

\[\mathtt{output}_{i_0, \ldots, i_{n-1}} = \mathtt{arg0}_{i_0, \ldots, i_{n-1}} + \mathtt{arg1}_{i_0, \ldots, i_{n-1}}\]

Backprop

\[\begin{split}\overline{\mathtt{arg0}} &\leftarrow \Delta \\ \overline{\mathtt{arg1}} &\leftarrow \Delta\end{split}\]

C++ Interface

class Add : public ngraph::op::util::BinaryElementwiseArithmetic

Elementwise addition operation.

Public Functions

Add(const std::shared_ptr<Node> &arg0, const std::shared_ptr<Node> &arg1)

Constructs an addition operation.

Output `[d0, …]`

Parameters
  • arg0: Node that produces the first input tensor.

    `[d0, …]`

  • arg1: Node that produces the second input tensor.

    `[d0, …]`
