Tanh

Tanh  // Elementwise hyperbolic tangent operation.

Description

Produce a tensor with the same shape and element typye as arg, where the value at each coordinate of output is the hyperbolic tangent of the value of arg at the same coordinate.

Inputs

Name Element Type Shape
arg Any Any

Outputs

Name Element Type Shape
output Same as arg Same as arg

Mathematical Definition

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

Backprop

\[\overline{\mathtt{arg}} \leftarrow \Delta\ (1 - \mathtt{output}^2)\]

C++ Interface

class Tanh : public ngraph::op::util::UnaryElementwiseArithmetic

Elementwise hyperbolic tangent operation.

Public Functions

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

Constructs a hyperbolic tangent operation.

Parameters
  • arg: Node that produces the input tensor.
