Exp

Exp  // Elementwise expine operation

Description

Produces a tensor of the same element type and shape as arg, where the value at each coordinate of output is the expine 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

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

Backprop

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

C++ Interface

class Exp : public ngraph::op::util::UnaryElementwiseArithmetic

Elementwise natural exponential (exp) operation.

Public Functions

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

Constructs an exponential operation.

Parameters
  • arg: Node that produces the input tensor.
