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.

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

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.

Exp()

Constructs an exponential operation.

Exp(const Output<Node> &arg)

Constructs an exponential operation.

Parameters
  • arg: Node that produces the input tensor.
