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

\[\begin{split}\overline{\mathtt{arg0}} &\leftarrow \frac{\Delta \cdot \mathtt{arg1}}{\mathtt{arg0}} \\ \overline{\mathtt{arg1}} &\leftarrow \Delta \cdot \mathtt{output} \cdot \log(\mathtt{arg1})\end{split}\]

C++ Interface

class Power : public ngraph::op::util::BinaryElementwiseArithmetic

Elementwise exponentiation operation.

Inputs

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

Power(const std::shared_ptr<Node> &arg0, const std::shared_ptr<Node> &arg1, const AutoBroadcastSpec &autob = AutoBroadcastSpec())

Constructs an exponentiation operation.

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

  • arg1: Node that produces the second input tensor.

  • autob: Auto broadcast specification
